Definitely. Best bet for suit selection is the Madison Ave. store (the Rhinelander Mansion), but the SoHo Prince St. shop carries a decent selection of RLBL suiting as well. If you call SoHo, ask for Anthony, he's very helpful.
Sorry, you'll have to define "good bargain." One man's bargain (e.g., G&G sale at Barney's) is another man's frivolity. Are you speaking strictly in terms of pricing or in terms of discount percentage, etc.?
