I was visiting for my cousin's wedding and had to get my nails and feet done. I come from Orange County where nail salons are on every corner but this one was by far the best one I've been to! Not only do they all speak english, friendly, and have great amenities - but they go above and beyond to make you feel comfortable and make sure you like what you get or else they'll do it over again, no problem! Wish we had more of these types of nail salons in OC.
Not sure why they have such bad reviews. I did notice that most of their positive reviews have been filtered. Probably Yelp trying to force small businesses to pay them for better reviews. Anyway, definitely give them a try, you won't regret it!
