My teen son and I were staying in an apartment in the Zizkov area and the locals recommended The tavern. It was very busy but we got a table (if we promised to be out in an hour) and we were not disappointed. A small place with a friendly, homey atmosphere. service very good, menu in English. My son claimed this was the best burger he ever ate. The draft beer and fries complimented the meal perfectly. Before we left we made reservations for the next day. You can eat for less money in Prague, but I won't complain because the portions were generous and very well-prepared.
