Craft Beer Co / Cask is heading to Brighton! The Spotted Dog has joined the fold and will continue to trade as such (so far as I can work out) for a couple of weeks, till "Cask Brighton" [that's a Twitter feed] opens on Friday 23rd at 12:00.
All 3 in the chain are actually owned by Greene King, although you wouldn't know from either the inside or the outside.
Here's a picture, and here's some cheap train tickets.
