Sam from nail lab does the best french manicure I've had in the city! I'm pretty picky with my french nails and I feel like most spots have little issues, like the tips are uneven, or the shape is asymmetrical or unflattering. Its not a big deal but when I get a perfect french manicure I take notice. This is 1 of 2 spots in the bay area that I've found. The other is sweeties in campbell but I can't keep travelling that far for a manicure. Highly recommend!

I have NEVER had someone be so precise and meticulous with my nails, 5+ stars!!! I’ve been trying to grow my nails out to get builder gel on my them as I tend to pick at them as an anxious habit. These turned out so beautiful and clean, and I can’t believe it’s my natural nails!! For still being on the shorter side they shaped them well. Will be coming back.

I've been coming here for about a year. I can't say I've ever been that loyal to a nail shop, but they really do a fantastic job over and over again. I'm embarrassed to say, I'm heading there now with a month of growth and not even one chip. Those are my real nails. Edit: another fabulous manicure

I had a really disappointing experience at this salon. I got my nails done right before my flight and paid $110, but the very next day two nails already came off. I immediately contacted the salon, but they refused to offer even a partial refund. Now I have to go to another nail salon to fix everything. Paying $110 for nails that didn’t even last a full day is unacceptable. I am not satisfied at all and cannot recommend this salon to anyone. :(

Will be making this my go-to salon. Gel extensions done beautifully and fast with a regular pedicure at the same time. Sam did a wonderful job on my nails and 2 weeks later (second picture) they still look amazing. I'll be going in for a fill soon.
