Not bad, not bad at all.
This is not a fancy spa. But it's clean, it does the trick, and the foot massages feel great. Just enough pain to be therapeutic and enough relaxation to put me into a zenned out state. As with many places like this, the therapists chat with each other during the massages, which is mildly annoying, but it's ok. I'd want to chat with people too if I was rubbing feet all day.
The price is just lower than what seems to be the standard, $18 for 1/2 hour and $35 for an hour. And it's open late, till 10 pm. So far I have not had to wait more than 5 minutes as a walk in.
If you're in the strip mall, definitely worth a visit.
