I have been coming here for years (my customer number is 116 and they're in the 7000's now).
Over the years, I have learned that Leon knows (waaaay) more than me about fitting suits. When he's pinning your jacket (and your pants) he knows what he's doing... You'll look great when he's done.
I trust him implicitly (he tailored our tuxedos for our wedding).
Turn around time is pretty quick too (about a week unless it's an emergency than sooner).
I honestly wouldn't take my suits to anyone else.
