By far my fave nail spot in the east end.
Totally affordable ($35 mani/pedis) and the service is top notch.
The decor is clean and modern - it looks nice enough that you might think it costs more than it does. The staff are all very friendly and will leave your nails lookin' their best. I've never made an appointment (they have lots of staff) but they do take resos.
In fact, I made a reservation for a bachelorette group in the summer. They gladly accomodated us and encouraged us to bring in our own champagne & snacks. I've been back a number of times since and would absolutely recommend it!
