Tasty food, but I'd say it's a little overpriced for what it is.
Location is perfect if you're walking around the old town. However, I wouldn't recommend if you're in a hurry, there's usually a long line. I tried coming at non-peak hours, the only problem is that many items on the menu are gone by then.
Groups are also probably not a good idea because of the wait and lack of large tables, but the place is perfect for a date!
