I only tried In Spa once but wanted a pedicure. I found that the minimal lower leg massage using latex gloves didn't provide any relaxation, the 30 seconds of pumice stone scrubbing on my feet left me with no fewer callouses and the nail polish began to chip within days. I've gotten better pedicures at much cheaper rates, I was not impressed.
Pros: Friendly @ front desk
Cons: , unconfortable seating, didn't feel pampered
