I'm tempted to plan a return trip to the UK based solely on visiting various BrewDog locations. Each -- well, at least the two we've been to -- were unique. Not just slight modifications on a them, but completely different menus.
BrewDog Sheffield's menu is a little smaller than the one we visited in Manchester, but every bit as good. The beer selection is pretty amazing (of course) including a great guest beer selection and a huge collection of bottles. It's an oasis in the desert for craft beer fans, though that pisses off the Real Ale people. Meh, they'll get over it.
And if you're not into beer, they've complete bar, too!
