I mean, you're really getting the same service that you get at every foot spot in town. I don't know why people are so surprised that they are more expensive but they're not getting anything different. They are more expensive because they are the only Foot Spa next to Lotus of Siam. Supply and demand hello! Normally I would have driven further away to get to a $20 Foot Spa, however I just didn't feel like driving and the cost to me was the additional $20 plus tip.
As far as the actual massage went it was great she did a fantastic job, and I never felt hustled for a tip. They did however forget to do my Yelp check-in offer for the free sea salt scrub, but I also didn't remind them at the end so it's my fault too.
