The fresh mango shake is delicious (just make sure to ask to prepare it with no yoghurt or sugar). They have the classic selection of south indian vegetarian dishes and Dosas. Instead of the paneer cheese they use tofu, so they should be vegan. If you do not eat ghee, ask them in advance and they will be happy to help you. They also have traditional food from Laos, fried rice and noodles. The price for a fruit shake, steamed rice and Malay Kofta (made with tofu) was about 4$.
