This guy actually specializes in men's clothes as well.
I've bought three winter dress coats from him.
They are high quality and Made in Italy.
Most recently, I was looking for a very think winter dress coat that went down to my knees (as opposed to my waist or my shins) and Sergio was so patient with me, allowing me to try on every single coat on the rack before making my decision. The prices are reasonable.
He is up on his competition, and constantly benchmarks himself against Harry Rosen. He is also very familiar with all of the Italian couture companies and even the threads that they use.
Sergio does not take his job too seriously as there are often one or two dogs roaming around the very large premises (they are very friendly Labrador dogs). Also, there is a seamstress onsite who is very polite as well.
