Very disappointed with a recent visit to Howl at the Moon on the RiverWalk. Shoddy drink mixing, bad sound mix, amateur entertainment. It is supposed to be a dueling piano bar. I've been in a number of those kind of places and they were always fun. Great sin-a-long action going on from top notch musicians. Good drinks to make the singing louder. But at Howl at the Moon they concentrate on 86 oz buckets of slop that kids use for speed drinking contests. The musicians sang all the songs too fast trying to get them over with so the sing-along just never was happening, especially with the drunk folks. The sound mix added to the problems because you couldn't hear the vocals over the instruments; pianos, drums, bass, guitars, plastic trombone, etc. And absolutely no interaction with the audience, though since we couldn't really hear them, even when they weren't playing we wouldn't have known they were trying to interact and joke with us.
Fair warning, if you want to have a good time, find somewhere else. Now if you want to get drunk fast on bad liquor...
