So I'm going tom be in Houston for business next week and I'd like to take the opportunity to relax at a nice spa. Whenever I'm in Dallas, I like to stop in at King Spa, which is the mothership of all Koran Spas in the US, apparently. Anyway, I notice there are two relatively recently open Korean spas in Houston now. Gangnam Spa and Spa World in Katy.

For those that have been to King Spa in Dallas, how do either one of these compare? How are the facilities you get with your default entry fee? How do the scrub/massage services compare? Is the Korean food at their cafes any good?

If neither one is worth my time, where would you go to relax and have a nice massage that stays open late on weekdays?
