Ballabeni is close to the university and has quite a following, as you'll see by the long lines it commands. I had raspberry and lemon basil and found them both to be excellent. Those with me also thoroughly enjoyed their selections. Nice addition were the edible bowls (like a very thin, airy almost tasteless cone but in a square shape). I can't say this is the absolute best - I found Bartu to be also very, very good and organic - perhaps I need to do more research!
