Denpasar, bali, indonesia

  1. Denpasar – Wikipedia, the free encyclopedia

    https://en.wikipedia.org/wiki/Denpasar

    Denpasar (Indonesian: Kota Denpasar, Indonesian pronunciation: [dənˈpasar]) is the capital and the most populous city of the Indonesian province of Bali.

    Etymology – ‎History – ‎Geography – ‎Demography
    .
    Denpasar market, Denpasar is the capital of Bali Province. The main street of Denpasar is Gajah Mada street where is the main shopping center, .

    Bali Ngurah Rai International Airport, also known as Denpasar International Airport, is located in southern Bali, 13 km south of Denpasar. It is Indonesia’s third-busiest international airport.

    Bajak Laut Nasi Tempong & Seafood, Renon, Bali

    Sporting the growth of Denpasar residents’ likes for Nasi Tempong, Bajak Laut Nasi Tempong & Seafood sets on a different kind of path by combining Nasi Tempong with the other well-known Bali’s best: Seafood.

    Sets in the cozy neighborhood of Renon, Denpasar, Bajak Laut is the newest addition of restaurant openings in this area. From the down-to-earth food courts selling Ayam Goreng, Chinese food and Sup Kepala Ikan, to the more luxurious XO Suki & Cuisine, Ayucious, or the more established Bendega, Ikan Bakar Cianjur, and Hanamasa, Bajak Laut further marks Renon as a leading Denpasar’s culinary destination.

    Though opened really close to the market leader Nasi Tempong Indra, that with its aggressive market expansion in 2012 opens two new branches around Renon area alone, Bajak Laut however has what Indra has not: various choices of seafood comprising of fishes, shellfish, crabs, and shrimps. Therefore market wise, Bajak Laut is aiming at a slightly different crowds: those who loves the spicy Nasi Tempong, and those who loves Seafood; especially those too tired to go through all the traffic madness at Simpang Siur to reach Jimbaran.

    (Or believes it’s too touristy.)

    As the champion of this premise, Bajak Laut offers “Kepiting Asap ala Bajak Laut”, which are crabs cooked in sweet and savory rubs, then grilled inside banana leaf wraps to enhance its aroma. The result is a treat not only delicious to the taste but also to the sight.

    Ingredients used for the rub is dominated with daun salam, or Indonesian bay leaves. For those familiar with gepuk; fried beef first marinated in spices and brown sugar, Kepiting Asap ala Bajak Laut has an almost identical seasoning.

    One portion of Kepiting Asap ala Bajak Laut consisting of two crabs weighing total of 5 ons (500 grams). At 120K they’re good for two, while the 7 ons one costs 150K. For the 5 ons portion, the crab size is a bit small, hence eating them requires quite an effort.

    Nasi Tempong is a good example how a food originated from outside Bali could becomes a local hit. Originated from Banyuwangi, Nasi Tempong managed to get quite followers due to its main character of super spicy sambal. Nasi Tempong usually served as a package consisting of white rice, steamed vegetables, tahu, tempe, anemic salted fish, and super spicy sambal, and a main dish of either fried chicken, or other kind of proteins.

    While I’m not a die-hard spicy food fans, I found their Nasi Tempong quite palatable, especially since the stewed vegetables plus sambal that’s the core of every Nasi Tempong dish, is like a staple food in Western Java where I grew up.

    Service is polite and attentive, though we found it’s a bit hard to get attention from the waiters, except from the one stand by the front door. Beside of the seafood, the Nasi Tempong variations are sold around 12K to 45K,

    Starting December 2013 but don’t know for how long, Bajak Laut Nasi Tempong & Seafood offers a special discount for their set menu, at 150K for 4 people, and 250K for 6 people.

    One annoying condition that we have to face as well, that even though the premise is fully airconed, people are allowed to smoke! And here in Denpasar, Bali, sadly it’s the common case with many eating premises, and Bajak Laut is no exception. Therefore while their crab is quite delicious, until Bajak Laut separates its smoking and non-smoking section it poses health hazard to your youngsters. (byms)

8 must-see places in Southeast Asia for great views: bucket list 2015

8 must-see places in Southeast Asia for great views: bucket list 2015
Southeast Asia is more than food and culture; here are 8 eye-candy places with magnificent views for a highly memorable trip!

Not just a melting pot of cultures, religions, history and food, Southeast Asia offers many picturesque spots that your eyes will thank you for. Whether it’s enjoying a sunset from a mountain top or just taking in the bucolic sights of Mother Nature’s hand-sculpted terrains, you’ll attest that these 8 suggestions offer some pretty unique charms that take your breath away.

 

1. Inle Lake, Myanmar

Myanmar has become a hotspot for the intrepid traveller and opens up plenty of opportunities to lap up many of its natural scenic wonders. If you’re heading there, a must-see place is Inle Lake renowned for its vast body of water where one can spot fishing communities and homes built on stilts.

Not only is the lake famous for its photogenic quality, you can hire guides to visit fish farms and shop at handicraft stores. Inle Lake’s picturesque charm comes from watching leg-rowing fisherman haul their catch during sunset. Find cheap flights to the capital Naypyidaw and best time to travel there is between November and February.

2. Tiger’s Nest Monastery, Bhutan

Perched some 3,000 metres above sea level and build in 1692, Bhutan’s Taktsang monastery, or more popularly known as Tiger’s Nest, is a must-see when you come to this nation steeped in Buddhist history. Getting there is not for the faint-hearted as one has to traipse through a hilly, rocky and undulating path to reach the peak.

Do hire guides to reach the apex successfully, and you’ll be rewarded by 360-views of sylvan mountain tops. Spring time from March to May is the best time to visit Bhutan and Drukair Royal Airlines of Bhutan flies theredirect.

3. Mount Kinabalu, Sabah, Malaysia

Recognised as one of the tallest peaks in Southeast Asia, Mount Kinabalu is a trekker’s dream come true. Getting to the summit takes about two days to accomplish. There is a 4-km climb to Laban Rata lodge where you can rest and replenish on sustenance. The next day is a 2-km climb to Low’s Peak.

The trek may be arduous but with lush rainforest terrain, there’s always something new at every corner to keep you distracted. About a kilometer away from the peak, the terrain changes to rock, stone and pebbles complemented by vegetation normally found in cooler climes. To catch the sunrise on the second day, it’s advisable to depart at 2am but remember to bring extra clothing as the mercury will drop to 2 degrees Celsius.

4. Palawan Island, Luzon, Philippines

Recently coined by Huffington Post as “The Most Beautiful Island In the World” while Conde Nast Traveler’sReader Choice Awards named it “The Top Island in the World”, Palawan island is quite the magnificent sight. With its beautiful azure waters infused with emerald hues, it’s also hard to refute such claims.

Dotting the waters are jungled-filled islands, each with a distinctive hill rising above the ocean. Just by half-hour domestic flight from Manila airport, once you soar above Palawan’s oceanic landscape, you’ll feel like you’ve reached Shangri-la. Whether it’s island-hopping or sea kayaking, fun-filled times are never in short supply.

5. Penang National Park, Malaysia

Penang is truly a foodie paradise but many people are flocking there for other reasons, one being its attractive natural environment. Located just west of mainland Malaysia, a flight from Singapore is slightly over an hour.

With plenty of diverse lifestyle choices and entertainment options, Penang also has its idyllic charms. Aside from its UNESCO-designated George Town, the Penang National Park located on the North-Western side of the island rewards one with rich rainforests, a diverse ecosystem and some 1,381 hectares of wetlands to indulge trekking fanatics and eco-photographers.

6. Tanah Lot Temple, Bali, Indonesia

Bali is never in short supply of mysticism and wonder. A two-hour flight out of Singapore is all it takes to enjoy a short vacation. And of course, visiting its picturesque sea temple on the west coast of Bali, Tanah Lot, promises many Kodak moments. A simple traipse during low-tide rewards a sight to behold too – a Hindu shrine ensconced among lush trees perched on a rock is postcard-worthy from any angle. Framed by crashing waves, Tanah Lot Temple brims with a dab of fable and mysticism that makes it a must-see when visiting Bali!

7. Angkor Wat, Siem ReapCambodia

Angkor Wat became even more famous, thanks to the Tomb Raider movie starring Angelina Jolie. Founded in the 12th Century, it is also the 7th Wonder of the World. This Khmer temple’s architecture will seize the gaze of any first-time visitor. At the centre of this city, within a moat, is a towering stupa that provides sylvan views of its 3.6km, vine-covered outer wall. Just 5.5km north of Siem Reap, the Angkor Archaeological Park is a must-see for travellers with a penchant for history and artefacts.

8. Halong Bay, Hanoi, Vietnam

Halong Bay, which means “Bay of Descending Dragons”, is a unique karst topography carved out by Mother Nature. The UNESCO World Heritage site offers views of vertical formations which are rich in dense vegetation. A boat cruise meandering through any of the 1,969 islets is both tranquil and insightful. Avoid the monsoons from June to September and from January to March, but visit the high seasons to enjoy sunny skies that won’t put a damper on your exploration plans of the natural outlying islets. After a three-hour fight to Hanoi from Singapore, take a five-hour road trip via mini bus to the port; it costs around USD 6 (SGD 7.50) and can be arranged upon arrival.

All these places will astound you in a multi-sensory way. Whichever activity you decide to experience at these destinations, you’ll agree that many good memories await.
