There is usually BBQ (and kickass free live music) every Wednesday (Honkey Tonk Hump Night) and whenever they have a special event/party thing going on.
Just checked their events page (re:HAB Bar on the Bayou
) and it looks like there's a big Soiree on Saturday. A KPFT (Pacifica) fundraiser with 7 bands & BBQ..then a new band on Sunday that cranks up at 4pm. And the weather for Sunday looks great...so far...but hey, this IS Texas.
Hope to see a bunch of you there.
