They prefer cash which is really frustrating. When getting gel make sure that you wash your hands after they are done filing. The nail tech did not have me wash and began to paint the clear coat of gel on and it looked like he was painting on sand. The polish was so rough and uneven. I had him start over since it looked terrible. They charged over $30 for a gel manicure which is high in my opinion. Nice color selection but I wont be back.
