I spent most nights in Recife,and there,the place I loved most was "The Performing Arts Space",Recife's prime theater venue,in the elegant "Princess Isabel Theater.
Nowadays I heard it's closed for renovations.
If you get there during the day, it looks a bit shabby... it is an openair podium and it could use a paint-job, but if you get there during the night... they have live music all night long, cheap bear... and a lot of locals
If you want to buy a beer, get a ticket first and then go to the counter, you will get a large bottle (1 liter) with some cups (so you can share)
Do not use the toilets they are dirty
