Went here for lunch with a coworker, and totally loved it.
The service is weak. The decor is weak. The process is confusing. The details are lacking. You get cheap paper plates. If you want water, there's a pitcher. It has about as much ambiance as a Circle K, and it would be easy to think they're doing everything wrong from a restaurant experience perspective.
But they totally made up for it with the food. I had the spinach dosai, and it was awesome (and I'm no vegetarian). My mouth is watering right now thinking about it. I wanted to go back for dinner that same day. (I actually want to go back for dinner right now!)
