Ah, the Dolphin! My mate had his wedding reception there - looked really nice! Mind you, I was the Best Man, and was a little worse for wear! ;)
You'll be right near the old walls then - there's some fantastic bits around there. Worth walking them all if you've got time... And right by the docks, too. There's some lovely bits of architecture and history around there that people who've lived here for years have never seen...
If I wasn't so up in the air at the mo I'd suggest a meet-up! Hope you enjoy yer stay. :)
