Wondering about the name? Well, The Mad Hatter was originally a gentlemans hat factory and shop, making hats such as the famous Bowler, Topper and Boater. The Mad Hatter, of course, was a character in Lewis Carol's "Alice in Wonderland" - which hosts reference to a myth that the glue used in the making of the hat rims contained Mercury. It is said that the Mercury dispersing particles so close to the brain would tamper with the molecules of the mind and therefore send people slightly mad. Thus creating the phrase "mad as a hatter". Now you know!
A lasting tribute to London's industrial heritage, The Mad Hatter was originally a gentlemans hat factory - where the famous Bowler, Topper and Boater hats were once produced.
