I was going to be a bit more helpful than the last reply
A pint ? there is the Alex in Alexandra Street, has music some evenings.
The Last Post but it is a Wetherspoons so you could have a long wait to be served.
Best to order all your drinks for the night in one go
Don"t go down the seafront pubs, not very pleasant except The Cricketers
which has strippers some lunchtimes.
If it is a punt you are after then you are out of luck for anything decent I am afraid.
