Full of expat Indian subcontinentals this place is the real deal. Lunchtime thalis are excellent value and are unlimited. The Al Khuwair spot is a snack spot only, The Ruwi specialises in chats and the other (Rex road?) in Indian-Chinese dishes.
Pure veg, although you need to know what you're ordering to get vegan as the waiters don't understand the concept so well. This is common in any Indian place in my opinion.
Cons: Thalis not vegan
