Mango sticky rice is popular all over Thailand so of course it's a part of Bangkok too. It can't go wrong, the rice is common and easy to make so anyplace you try it it will be good. Combined with fresh, sweet mango creates outstanding flavor.
Kulfi is better than ice cream and they had great idea to make it as countries of southern Asia are very hot therefore regular ice cream would melt within seconds. Kulfi lasts a few good minutes which is enough time to gaze, talk and eat really slowly.
