Got some Bermondsey Tonic Syrup today from the East London Liquor Company in Hackney, London.

50ml Adnams Copper House Gin
25ml Bermondsey Tonic Syrup
100ml Soda water

Makes a damn fine G&T. It ends up something like Fevertree but with some woody notes and a bit more bitterness. Recommended. The brown colour comes from the Cinchona bark that is unfiltered. Some might find that a bit off putting!

They also suggest a short cocktail, 35ml Gin, 35ml BTW syrup, dash of bitters and lime. It'll be interesting to see how that works out.

Google doesn't seem to like me posting links to alcohol so find it at btw-drinks dot com

Also picked up a bottle of the ELL's standard London Dry Gin but I haven't tried that yet.

Adnams is a long established brewery of real ale on the East Anglian coast. In the last few years they've branched out into Gin, Vodka, Rum and even a fortified 20% ale thing. They're gin is lovely both in standard 40% and export 47% versions.
