Yes there are. I usually ride with guys that wouldn't be caught dead (or maybe they would!) in a biker bar, but I've been to a couple good ones. Most are fine, if you don't act a fool, and don't stay too late. Also, leave the old lady at home if you are going biker bar hopping. They like to share.
Some real rough joints out on 80, west of 820. My favorite is Niles City Saloon, because the owner is a cop. Horny Toads is next, but the crowd is weaker. The bars on the other side of 80...I would not drink there.
Eagles Nest up Boat Club Road can be good on the weekends, and a little further, The Spot. It's not an official biker bar, but if you like rough chicks singing karaoke, give it a shot. Cold schoonies!
The most real biker bar is right there heading out of downtown, toward I-35 N. You have to make the sharp left and turn around to head north. I've only been there during the day.
Redneck heaven on 820 at Beach is becoming more biker popular. The construction is keeping lots away, but the crowd is always there. I got comped a $70 bill for poor service. Not all tatted up shortshort and bikini top wearing girls can wait tables.
If anybody wants to get a fair weather ride going sometime, I'm in.
