This Houston mainstay with the classic, old-school-Vegas-style sign is celebrating its 25th birthday this year, and you should help with the festivities. Turns out the sign is actually the only over-the-top, glitzy part of the Colorado — unlike most other Houston gentlemen's clubs, this one strives for the warm, comfortable feel of a hunting lodge. The decorations include stuffed and mounted wild game and grand pianos. It's a refreshing change of pace from other such places, which tend to look strikingly similar inside. You might come for the beautiful women, but you'll stay for the billiards, terrific menu, and cozy, friendly vibe. Here's to another 25!
