Review: I had read about this place on happycow, and here's my Cha-Ya Berkeley location review. Was here on a past trip to San Francisco & the Bay Area. My husband and I came during dinner hour, and it was packed. We waited a short while for our table. The space is very small with limited seating. There are a few tables plus sushi bar seating. The food is reasonably priced and very delicious, authentic vegetarian Japanese food (all vegan suitable). I enjoyed the Cha-Ya rolls and the soba noodle soup.
