I go to Schminkbar once in awhile (http://www.schminkbar.ch). I've never had a facial there but I've been pleased with other cosmetic stuff. They have a nice relaxed vibe, the chairs and sofas are comfy, and you usually get free tea and a little fruit-skewer or something like that. Prices seem reasonable to me, but I don't go that often so I'm not good at comparison shopping.
