Pure / Perla doesn't have 45 minute sessions. Session at both locations are $150 for 40 minutes, which actually makes it the least expensive of the spas you mention! It's $180 for 45 minute at Muse, Seduction and Flirt. When you consider the fact that you are most likely to get your full time at Pure / Perla, and the general quality of the girls and service there then it's misleading to say it's the priciest. It's actually a pretty fantastic value when compared to what you get at the other major spas.
