In Short If you consider a trip to the spa that one-time indulgence that guilts you for months, this might be the place to convince you otherwise. The chain operates on the premise that monthly massages are crucial to one's health, enticing clients with affordable memberships for one-hour Swedish, Deep Tissue, Sports and other rubdowns.

Throw in late weekday and weekend hours and the only missing ingredient is that there aren't more of these shops across the city.
