Envy Nail Spa is clean (mostly) and what you would expect for the price. My only complaint is the service isn't consistent between the nail technicians. It's basically hit or miss with who you get. Some of the techs seem to have regular clients, but I suppose that's my own fault as I only end up going when I glance down at my toes and gasp at how hideous they look.
Also, although the prices are reasonable here, salons in this area in general are very expensive compared to any other big city. I realize it's all about supply & demand, but Pittsburgh needs more nail salons!!!! Ok, back to Envy ~ beware of Saturday mornings/early afternoons as you'll end up waiting a while for a pedicure. Also, try to get a pedi chair that is closer to the front of the studio. The ones in the back tend to make me feel claustrophopic
