Atlantis spa is as generic MP as you can get. Higher prices than AMPs and less service oriented. Typical vanilla service, but I get it - sometimes you just want to bang a non-Asian (ie. white) girl. For that reason, I've been to Atlantis on several occasions over the years. Not much to ever write about (next to nothing massage, small chit-chat, cbj for a few mins, NO daty or bbbj, and finish in mish/doggy). ONLY plus side for me is chance opportunity to bang a college age, Cactus club type, white girl. No guarantee of the latter, as another pooner stated - pics are fake. Cheaper than the 1122 downtown girls who are GUARANTEED to be Cactus Club-looking-quality girls but do bbbj, lfk, etc.

I don't want to go to Tiger every week so Atlantis and Great Pharaoh provide other options.
I too haven't seen Viridana (or at least i don't "think" I have; I'm crappy with names) but I recommend go check her out and report back - if worthwhile.
