Pal Zileri

If you are looking for high-​end men’s clothing and superb customer service, this shop directly across the street from Harrod’s is the place to go.
We were visiting from the U.S. and I had looked at virtually every shop in town for a specific style of tuxedo without success. When I described it to Mr. Cleary at Pal Zileri, he said he didn’t have it in the shop but that he could have it there the next day. We returned and indeed, he had brought in the perfect suit in two sizes for me to try. The minor alterations were performed and the suit was ready for me the next day.
Their goods are very high quality — beautiful fabrication and superb tailoring — and the service is very British in all the best senses of that term.
