I would say breakfast then ... it's excellent !! We're going to be there for one breakfast and one dinner this summer. Check out the menu on the allearsnet site !!
We haven't been there for several years, but breakfast at Boatwrights stands out for us as the best breakfasts we've ever had at WDW (and that includes the AYCE smoked salmon at Spoodles!)
Have not had breakfast there - but we had dinnerinner there the weekend after Thanksgiving '05 and we all agreed it was the best dinner (including DD13 and DS10) we had anywhere and we do at least one TS each day.
My DH LOVES the breakfast there! It's just way too inconvenient for us to get there from the Yacht/Beach club when we go that we're nixing it this time around.... last time we ended up walking to MGM and then hopping a bus to Port Orleans in order to get there for breakfast- a good hour at least in travel time to get to breakfast!!LOL! We do love the food there for breakfast!
I was there in October and we just had a horrible meal with bad service to boot. I normally love Disney restaurants and was so disspointed. If you have to eat one of them there I would say breakfast.
