This place is one of my regular routines. Their mani/pedi's are inexpensive (~$30), all of the employees are super friendly, and they really try to take care of you. The skill level is varying - some days are better than others, but I'm always happy with the results for the price. They also have convenient evening hours (open til 7) and weekends (I think they are open Sundays in addition to Saturdays now). Granted, this is not your high-end salon, but for just giving yourself a little treat, US Nails in Redmond is a decent place to go.
Pros: Inexpensive, friendly, decent mani/pedi every time
Cons: Off-street parking can hard to find sometimes
