Had dinner there a couple of nights ago. Friends of mine ordered the "Wajwan" fixed-price group menu, though because I'm a vegetarian our waiter graciously made substitutions for me for the meat dishes.
Overall, the food was tasty and creative. Definitely not too authentic in my mind -- the spices seemed to me to be too delicate, too mild and self-effacing to be the powerful mixture Indian food is in my mind. But because of this gentle, carefully-arranged quality, each dish had that gourmet sense where you could taste all the different flavors and appreciate how they came together.
The food that stood out as best to me were the breads, which were highly inventive and well-cooked, and ranged from rosemary naan (the fluffier, thick bread) to corn roti (a flat, dense bread). I also enjoyed an eggplant puree. Possibly best of all was the dessert, a fist of peanut butter kulfi (indian ice cream) on a popsicle stick, covered in chocolate, and complimented by two long peanut butter cookies. Delicious.
A few other entrees fell a little short. The squash curry simply wasn't all that great, and the saag paneer (spinach + indian cheese) pizza was too heavy in taste and texture. Then again, I had already eaten a lot by this time. I may have been biased.
Overall, the Bread Bar was an enjoyable experience and I would go back without hesitation. Definitely better in my vegetarian mind than some of the other high-end Indian fusiony places like Devi or Tamarind.
