We are going to an afternoon Wedding soon. The evening plans are a little sketchy and we know there will be a meal in a local restaurant (not sure what time or where) and the young Bride and Groom will be with many of their 20 year old something friends, so us old farts might need to gracefully leave them to it at some point. We'd possibly like the option to go to a half decent pub or bar. Any recommendations, thankfully received.
