Perhaps it is because I come from a smaller city, but I love Lakeview Tower for manicures. It's relatively cheap, the service is quick, the technicians are friendly, and my nails turn out really well each time.
I love that there are lots of shellac colours to choose from, and the technicians shape my nails nicely and paint them very carefully... A sharp contrast to manicures I've had at other salons.
If you're looking to get in and out, go at a down time. I usually go on a Friday or Saturday night when I'm not busy but the rest of the city is getting ready to go out for the night. At around 5pm, you can be in and out quickly!
