Living in Austin (round rock currently) for about 20 years, Texas all my life. Lots of strip clubs here, those that serve alcohol and those that don't. Those that don't, the girls go full nude. You can bring your own alcohol (beer or hard liquor) into those that don't.
worst strip club i've ever been to (having been to some in Vegas, NYC, South America) has got to be
lerougeboutique. Went in once for a guy's bachelor party, he wanted the dirtiest place and this was it. i can't describe how bad it was beyond this. Imagine walking in and seeing someone's mom. Not the hot mom, the stay at home house wife that doesn't take care of herself. She's walking around in a leopard print panties i guess, can't remember if her top was on at the time or not, but 45 year old unwanted titties, and a bottle beer in one hand, and a half empty 6 pack in the other. There was one hottie there, she wasn't working but a customer. there's a swinger's club a few blocks away, my guess is her and her biker boyfriend were going there later.
the rest of the strip clubs in austin are fine. i can't say any better or worse than the girls you'd find in vegas. The one thing about the big clubs in vegas is they have 100s of girls walking around. Most clubs in Austin or Houston will have 10-30. there's 1-2 types of champagne rooms in Austin and Houston. There's 5 or more levels in Vegas. In Vegas, tip the waitress when you get to the 'private' room. even if you don't get a drink, just water or something. There's small rooms that are semi private, tipping the waitress will keep your room empty and the other rooms will get multiple people.
