Barritt's Ginger Beer

[beeporama]

I've seen Reed's Ginger Brew in several places, but I'd like to have a "genuine" Dark & Stormy. Do I have to mail-order, or does someone local stock Barritt's? Preference for east end (I'm in Regent Square).

(Note: Ginger beer is non-alcoholic, and this is a Bermuda-made brand; it would probably be a food importer or grocer. I have looked a few places...)
