The Gate is the complex we're Tiger Tiger is. As you say, there are a number of pubs in there.
A few nice bars down on the Quayside, and over the river from there you have Buffalo Bills club (not a fan myself)
Blu Bambo is good.
Digital is probably one of the better clubs - Its near the life center, and is a good size. Not been in for a while though.
Strip Clubs:
Ive heard that Blue Velvet is ok. But never been to it myself.
Theres a one just of the A168, but I cant remember the name of it. Will have a think and get back to you.
EDIT: its called For Your Eyes Only. It supposed to be ok. But again, Ive never been.
