Elan is my go-to salon for manicures and pedicures. Regular manis are $12, and gel manis are $30 - plus a $5 charge for French tips. They also do combo deals for mani/pedis or when you have more than one service done - I believe my most recent gel mani and normal pedicure cost me $52, before tip. All in all, pretty reasonable for other prices I've seen/paid around town.
The salon is pretty good with walk-ins, but I've began making appointments as every artist there does things a little differently. They are all pretty good, but I've found Phoebe does my nails the best (or at least the best for how I like them). She's also very friendly and good to chat with as the appointment goes on. You can usually get an appointment within 24 hours of calling for one, and Elan has a good range of colors, both regular and gel. My gel manis last anywhere from 2-3 weeks when I get them done here!
