My daughter and I were in Prague a week ago and we had dinner one night at Bila Vrana which is located at Jagellonska 10, Vinohrady, 5 minutes from the Metro Jiriho z Podebrad. I had checked it out on the Internet and it certainly lived up to my expectations..
The food was excellent, the wait-staff were very pleasant and spoke to us in English and provided us with English menus. I think we were the only tourists present at the time though I hear it is very busy at lunch time. One could sit indoors or at an out-door patio.
We loved the food and found it Mediteranian-style. We had a starter of Prosciutto - with pickled Mediterranean vegetables, grated Parmesan cheese, rocket, artichokes, olives and sundried tomatoes. My daughter had pork tenderloin stuffed with a jalapeno pepper and I had lamb steak with grilled vegetables a provencal pesto - yummy. The prices were very reasonable.
I would definitely recommend this restaurant.
