My wife and I will land in Prague on her birthday, which will be a milestone. Knowing that we will be thoroughly jet-lagged, can someone suggest a special celebration/treat (beyond the usual dinner/dessert) that a tired couple might enjoy? We are staying in the eastern side of Old Town, and are arriving in late April mid-week. We are a "mature" couple who have never been to Prague before. We'll also probably shy away from drinking alcohol/spirits on the first night. Please let me know if I can provide any more useful info.
