I went to this place with my friend during when I was very interested in the Indian culture. She had told me that chaat is very light, small foods much like dimsum. She brought me here to Chaat Cafe to show me how good chaat was, and indeed Chaat Cafe was indeed delicious.
Because Chaat is small "finger" food, the prices of chaat are not much, so the prices here at Chaat Cafe were very reasonable. Many of the items were good, especially their puris. Try their puris with a little mint-chutney and tamarind sauce-- and you'll be set. The location is very central on University Ave. in Berkeley. From the outside, it looks very urban but inside, it is cute with little Indian decorations which made me feel like I was in a chaat house in India! The atmosphere is great here, and I recommend this place!
