Riva Cucina has the best Italian food in Berkeley (in my opinion). I was introduced to local beans Due Torri there, and I'm not sure any other place in the Bay Area carries them, as far as I know. It is a great place to have lunch, when in the east bay and the service is great :)
A super nice wooden deck/roof & plants area recently added to their outdoor tables, and I think it looks great! Large bike rack outside, triple points!
