After a long week at work, an hour on the massage table could be your cure. Finding a masseuse, however, is another matter. Your best bet is to check out Massage Envy, a national chain with 26 locations in Houston. We're familiar with the store at Buffalo Speedway and Westpark Drive, where "membership" costs about $50 a month. That gets you one massage — same-day appointments are usually available — and any additional massages run about $40. That rate probably isn't the best around town, but it's better than most. And the best part: Massage Envy stays open late on the weekdays, making it maybe the only late-night massage joint in town that won't get raided by the vice squad.
