Absolutely amazing.
Had a bespoke 3-piece suit handmade with English Super 140s wool for over $850 less than a 3-piece Canali that I purchased from Korry's down the street - a Canali that was pre-made and had to be tailored, and is now back at Korry's to fix some of the tailoring they did when I bought it.
Mr. Caruso's suit is beautiful, fits like a glove, and all of the details are perfectly done (i.e. pinstripes lined up at the shoulder seams, extra stitching for strength on the surgeon's cuffs, just enough padding to square off my offset shoulders, etc.). He's knowledgeable and can take you through the details of every fabric in the store. I've already ordered another suit to be made and will probably have 2 more made in the new year.
He also did an excellent job of tailoring a suit I purchased from Moore's a while back - he took it from baggy to fitted and it was ready the next day. Alterations are on the higher end of the price spectrum, but the quality of the work that goes into them is definitely worth the money.
As for service, I don't know what happened with the other reviewers on this site because I've been treated well from the moment I walked in with a suit that needed to be altered. Unlike some other men's stores, there was no pressure to look at or buy anything. I ended up ordering a suit simply because a certain fabric caught my eye. I had the same great service before I said I wanted a suit made, so I know that they are genuine and not nice only because I bought a bespoke suit. It's a family business and the banter between Mr. Caruso and his kids is hilarious.
I won't go anywhere else anymore.
