^yeah she used to call Mo's 'A Place For Ho's'
Just like every other major city on earth Houston is no different. There's dozens of places just in the Galleria/Uptown Park/Highland Village/Upper Kirby areas where UTR working girls can be found. Almost every upscale lounge or steakhouse at happy hour. In other cities throughout the U.S. and rest of the world a 4star+ hotel bar is a good spot too, though not really in Houston for some reason.
Just look for the hot girl drinking alone and paying extra attention to the upscale fat old ugly dudes chatting her up even though she's obviously out of their league.
Examples include S&W, Trulucks, Capital Grille, The Tasting Room, Eddie V's, Mo's, The Palm, etc...
Too much work for not a sure thing imop but it can be done and does provide the illusion of the 'thrill of the chase' I suppose.
