These days, Bates Hatters operate from the premises of Hilditch and Key (73 Jermyn Street). This unfortunately means that space is fairly restricted, but they seem to have a big store room and can retrieve almost any hat they got even if it is not on display.
The quality of Bates hats is very good, and they choice of different styles is just overwhelming. However, nowadays, the demand for gentlemen's hats is reduced to special occasions, and therefore a shop of this caliber is under threat of getting completely obsolete. Additionally, its biggest competitor, Lock Hatters, is just around the corner on St James, and they do ladies' hats as well and seem to survive on the Ascot business.
Price-wise, Bates comes in a little cheaper than Lock (prices vary considerably between different hat styles), and the quality in my opinion is just as good.
A great shop for an anachronistic product !
