I liked the atmosphere at the one on Stockton Street, but it is incredibly small. Not great for walk ins, as it's really hit or miss whether they are there, even when it says they're open. Last time I went, they told me they've had lots of turn over.
Lately I haven't had much luck in any nail salon in Riverside/Avondale. My best friend and I get our nails done together every two weeks. It's the only chance we have to see each other with our busy schedules. Lately we go up to Secret Nails in Orange Park. It's just past the Oakleaf Town Center on other side of the street. DON'T let the men touch your fingernails, although they seem fine with pedicures.
However, if you find one that's good, I'm all ears! Let me know.
