Happy Valley Nails and Spa is the best nail salon I've ever been to. I moved to Arizona from Michigan in July. I went into three other nail salons in the area, and wasn't impressed. When i walked into Happy Valley Nails it was packed! That is always a good sign as it means people love going there. I asked for a manicure right on spot. Luckily, i got the BEST girl, Kiu. She always fits me in and is amazingly talented. I've been going there every two weeks since. I like to get fun designs on my nails and not only am i always satisfied i am also impressed with how amazing my nails look. I recommend this salon to everyone! I always have amazing service. All the girls are very friendly and the salon is always clean. I even moved to a new place that is farther away and i still drive to Happy Valley because i am so happy with my experience. If you pay with cash you get a discount since you can't tip on a credit card. I just LOVE this salon and Kiu!
