How about one of the Pergolas in London? The new Olympia one is pretty cool. Would be good to be in a venue much bigger than the social, so that all the other customers get curious…they also have a Patty & Bun in the corner. Oh yes. The Prince in West Brompton is also awesome - done by the same guys. They’ve bought a corner pub and the five shops next door, and connected them all to an enormous covered beer garden. One shop is for coffee, and the other four are rotating food popups. Very cool idea…and again, a huge capacity.
South Wales for sure, there’s some good places in Cardiff for meet-ups.
I’ve specifically heard Tiny Rebel Cardiff is popular, they have separate rooms that can be booked out if required.
It would be good as the team from the Welsh office can join in too!
