Simple enough: live jazz/blues/rock every night between Tuesdays and Saturdays in a dimly-lit, cavernous basement bar. Despite its location being right outside Gozsdu Udvar, the passage teeming with popular bars and restaurants, Lámpás feels a world away from the tourist herds - a truly little gem in the midst of it all. Expect increasingly more dancing, a boisterous crowd, and a cramped space as the night progresses. Note that they usually scale back the operations in the summer months.
