Nail Envy is a great little nail shop in the unassuming Mt. Lebanon Shops strip mall.  My critique of a nail shop or spa is typically centered around the cleanliness of the shop and equipment, and whether I'm treated to personal attention or not (am I juggled between other clients).  \n\nNail Envy meets my cleanliness standards, I've never had to turn down the full mani/pedi for just a polish change (as I've had to do in other establishments once I saw their tools!).  No, they keep their shop, tools and equipment in tip-top shape and I'm never nervous to have them really go to town on my cuticles or roughed-up heels.  \n\nI've been here three or four times now, always as a walk-in (no pre-set appt) and have not yet had to wait at all.  There's always been someone available to take me immediately and they've never juggled me and another client, I always get my own nail tech personally dedicated to me. This makes for a much more efficient and speedy mani/pedi and as I'm usually in a rush...I appreciate this.  \n\nA tip: I once went in and got just a pedi (as opposed to my typical mani/pedi combo) because I was in a hurry....it was the same price as the mani/pedi combo and I felt sort of cheated.  For the best value, get the combo...the pedi price alone is a bit steep.  \n\nAlso, although they do accept credit cards, tipping can only be done with cash.
