Minh In Stitches.
This is a great convenient place to go to get hemming taken care of. Located right next to Kmart in the Parkway Center Mall, Giant Eagle is on the other side of the building. My mother, who is not easily impressed, has gone to this nice lady for quite some time. Her work has been good and fair, and I intend to go there as well. When I'm shopping for clothes, if pants are too long, i think, well, just take it to Minh in Stitches. Very nice lady runs the shop.
The lady/owner will immediately tell you how good she is. Then she will tell you how bad others' work is, even if no work was done on your clothes (she will badger you to convince you). You will then be put into a dirty dressing room (watch out for pins and debris - the place is not clean), measure you or takes a guess, and then it is all about pricing. She will overcharge you for subpar quality and wants paid upfront.
For me, she hemmed a pair of pants, it came out, and she swore it was not her work due to the thread used. She went in the back, came with her thread, and they were the same. She tried to tell me they were different and she didn't do the work, but I know for sure I had brought the pants to her prior.
I would advise shopping around for another tailor - just google one or use the phonebook. The convenient location is not worth the hassle or poor quality.
