I haven't been to the spot you mention, but I have had chaat at another chaat house in Berkeley (really, are three "e"s absolutely necessary in the word "Berkeley"? One seems like the mandatory minimum. I could accept two; leaving their placement up to the citizens of that fair city. But three just seems pompous and grandiose. I understand that Berkeley is a university town and, as such needs to establish itself above the common rabble, but come on; at least two of those "e"s serve no pronounceable purpose whatsoever. I smell a "Lose the 'E's" movement in the offing), Chaat Cafe at 1902 University Avenue. It was very good food, and because of the smaller portions, gave our group an opportunity to try more dishes.
For those of you not familiar with chaat, think Indian tapas or dim sum; small sharable portions of many different dishes with prices reflecting their reduced size.
As with so many West Coast trends in general, and food ideas in particular, I predict chaat will be working its way east at a steady pace over the next few years.
But I think they could stand to lose one of their "a"s.
