I use the dry cleaners at the corner of Mass Ave and Cherry St in Porter Sq (the name escapes me) . Very courteous and nice people, I've only had pants done (hems and waists) but they did fine with those. Just picked up a pair of corduroys $1 0 for a hem job that he troubled to double stitch because it matched the original. I don't know if they do more complicated tailoring, though.
