There is a spot in Brooklyn called T.S.B. T.S.B is an acronym, but if you're there, it's impossible to miss. It's on the corner of Kings Highway and McDonald Ave. and only ever opens, from what I've seen, past 9-10pm to about 4am, 7 days a week. I'm pretty sure it is a ficha bar from the double black doors, and I've yet to step inside. I figured I'd put it out there since I can't find any information on Google (that's why I'm keeping it an acronym. Maybe that's why they're still open every night), have no experience with ficha bars either but the place fits the description of places you guys mentioned in this thread.
Good luck.
