No dress code.
Not sure what bar we are in yet; Big pony usually lets us know on the day. It's on several floors. We've been in the non-smoking bar on the 3rd floor for the last few. Don't worry though, they usually sign post the way with 'URWFRC' unless it's in the bottom bar at the back. I'll email you my work number.
By the way, I loved the piccie that Peter took of the group, it's just a pity the 3 hombres weren't around for it.
