Rocky does a really excellent job with alterations and dry cleaning. He has hemmed several of my slacks, suit pants, jacket cuffs, and a coat. He has expertly handled my jeans and more delicate clothing like fine suits. You will not find a better tailor in the city. My dry cleaning also comes out nicely (as one would expect).
Rocky's is pricier than other tailors and dry cleaners in the city, but you pay for what you get. Parking in the back of his shop is convenient and rarely fills up.
