I've gotten many pairs of slacks and jeans hemmed at this shop. They do an excellent job. The height of the pants always comes out exactly where it's supposed to be. They usually ask me to pick up my slacks in a week, but I think they can do it faster if you request it. Jeans that I recently took here to shorten cost me $12 to hem, which isn't a bad price for a $65 pair of jeans. Make sure you bring the right shoes and belt to get the best length pant leg, when you take your pants in to get hemmed.
Pros: Quality work, not expensive
