I've used this shop many times, and have had a few problems: the length of my plants wasn't right, or when clothing was altered it didn't feel right. I kept using it until I had to take a pair of pants to be re-done and the lady, who's usually super busy and tending to 10 diff clients at the same time, was short and rude, after all the business I'd given them in the beginning.
Pros: if any, sometimes you get your clothes back sooner than other places.
Cons: Poor customer service, unreliable services (sometimes you get what paid for, not the best), hot as hell in the summer and not clean or presentable at all. otherwise...
