The John Hewitt is well worth checking out, but frankly I'd be happy staying in The Crown, especially if Belfast Black is on.
The Bridge House varies. Sometimes it's a quiet and civilised, if generic, Wetherspoon; and sometimes it's the sort of place that would make a denizen of Mos Eisley cantina walk out in disgust. But you'll know which mode it's in as soon as you stick your head in the door.
Bittle's is nice, if you don't might slumming it on the beer front a little. They have a decent bottle selection. There's a similar deal at the Duke of York.
