The Wetherspoons 'Beer Festival' which is currently running has a lot going for it.
There's a reasonable mix of beers from all over the country (including the usual 'International' offerings which are all actually what the Yanks call 'domestic' but we'll gloss over that) and a fair range of styles from which to choose.
Having sourced both Vienna- and Mรคrzen-style lagers on cask would seem particularly daring for Spoons, and indeed both are worth seeking out (more on why that may be less easy than it sounds in a bit!)
