I've been here a couple times now and they're usually quite busy. They DO accept walk ins, but just like any other place, it's not guaranteed as they can't take anyone in right away when all the technicians are preoccupied with other customers. I've made appointments and walked in too. I was taken care of in reasonable time. Their service was professional and neat. Ive never left unhappy so, I'll be returning often to collect stamps and get a discount to treat myself some more.
