I really liked this restaurant where I've been twice in a week. It's close to the castle, in a quiet area, with a very nice terrace.
The girls there were really informative, explaining everything, smiling, with a great english. I felt like a long-time customer.
The food was pretty good, there is a lot of choices. I wanted to try everything! The desserts are particularly good.
It's a little bit expensive compared to other places in Budapest but still very cheap compared to Europe.
A good choice when you're in Buda!
