This enormous theater is more akin to a Broadway production hall than a traditional tango salon, but the dancers are fantastic and the owner, who clearly loves to perform, is a good singer. The walls are decorated with photos of what appear to be every celebrity who's ever visited Buenos Aires -- and all seem to have made it to Señor Tango! Diners choose between steak, chicken, or fish for dinner and, despite the huge crowd, the food quality is commendable. Have dinner or come only for the show (dinner is at 8:30pm; shows start at 10pm).
