Vatican Citys No.2 Keeper
Rebels & Albion
For this, the Rose and Crown would also be in consideration. Slightly further walk from town on Montague Street, but also has the benefit of being next to the Mahaan curry house if you end up having enough drinks that you feel the need for some grub.cheers - definitely a boozer rather than a bar. the kind of place that hands you pork scratchings when you ask for the menu and has regulars who will probably resent my presence at the bar...
Otherwise, co-sign on the New Amsterdam for centre of town and The Goose for the seafront. Former also has the benefit of their kitchen being run by the superb Yeastie Boys Pizza Cub, if that takes your fancy.
