Hillside is alright for dry cleaning, but I absolutely cannot recommend it for alterations! The week before Thanksgiving, I brought in a jacket that only needed its zipper replaced, which should have been very simple. I was told it would be finished in one week. Well, it was finally finished the weekend before Christmas (and the only reason it was done even then was that I was standing in the shop, firmly telling them that I needed it before leaving town for the holidays). Every time I came to pick it up I'd hear a different excuse as to why it wasn't finished, such as the seamstress had ""left early"" for the day, or ""yeah, it isn't done, but it will be tomorrow..."". When all was said and done, the staff did seem sorry and apologized for the delay, and that's the only reason I'm giving it two stars instead of one.
Pros: Convenient location
Cons: Unreliable, unprofessional, did not finish alteration when promised
