Bar Fun Fun is a fun little bar with live music shows every night. Stop by and make a reservation a few hours before the doors open to insure a table. The shows start nightly at 10:30 and by 10pm the place is already packed. The night I went to Bar Fun Fun there were Tango dancers and singers performing live.
The food is typical bar food - nothing to write home about but the ambiance is great. They have typical Uruguayan beer and other mixed drinks. Keep in mind that the show is not free. They will include it in your bill and I think it was about 95 pesos per person.
