I feel like I've been to almost every foot spa in town. The price range will typically show you what you're getting. A $20 will get you a full body, typical Chinatown rub down, but the ambiance of facility is a gamble. A $30 or $40 Will get you the exact same thing, but I'm a spa with a more desired location, or slightly better ambiance. The quality of the actual massage is 100% dependent on masseuse.
XY foot spa has a great location and a great ambiance. A tranquil aquarium in the middle of the communal chairs gives a nice white noise to the other patrons. My masseuse was excellent. Hitting all the right spots and perfect pressure.
The only reason I took a star away was because when I got there, I asked about the $20/hr basic massage yelp check in offer. The man at the front told me that was $20 for feet only, if i wanted full body I should do the $30. Now I know this isn't true, and that no one is getting a full hour of feet only, but I didn't fight it and just paid the $30.
