Nightclub is the Angel, best place for fish'n'chips is probably Hadleys just over the bridge on the corner - they've just expanded so have a bit more room. We used to go there all the time now go to the other one on the left past the newsagents as they have more 'buggy' room.
If you can't find anything to photograph in Whitby there's something wrong. lol.
Oh btw, good luck on finding somewhere to park unless you are going by train.
Plenty of pubs, but there's a nice café in Sanders Yard (near the health food shop down Church Street)
Going thee myself with our lass and the young'un on new years day - was going today but couldn't be bothered.
