Tough choice, I've never eaten at Boatwrights so can't comment on that one.
Capt'n'Jacks - Service was good, quite a noisy atmosphere. I had crab cake to start and it was fantastic, but had salmon for my main which was awful. So dried out it was untrue, served with some pretty tasteless rice. Dessert was ok.
Planet Hollywood- only had lunch here once a couple of years ago but it was ok. The portions were huge, we shared I think a spinach and cheese dip for appetiser and it was good. The mains were both just ok. I enjoyed checking out the film stuff though.
