Correct. There actually seems to be a lack of regular bar/pubs in most of the Bronx. That could change, but as of now it's nothing like even Bed Stuy in terms of nightlife.

Another thing is that most of the South Bronx was destroyed during the 1970s arson wave, and the buildings were replaced in the 80s and 90s with cheap looking Fedders houses. So it doesn't have that homey feel that Bed Stuy, Bushwick, Harlem, Washington Heights, etc. have. That's also why, in my opinion, Brownsville is of little interest to gentrifiers.
