I have been going too Matrix for years now. It is true they only accept cash but it is only so they can keep their prices low. Every now and then while traveling I will get my nails done somewhere else because I have to and every single time it makes me appreciate Matrix all the more. They truly are the best at what they do. Recently I left the salon and put my shoes on too soon and ruined my pedi. I went back the next day fully prepared to pay for a fresh pedicure and they fixed my mess up for free. They are also great at fixing a broken nail if you just want a traditional mani. They are always super busy around lunch so I recommend going in the morning or late afternoon during the week. Friday and Saturdays are their busiest so I avoid going then.
