Since the OP mentioned the lobster roll, I looked up the menu online on their website (not the disney dining page).
I just looked at the boathouse's website and it has 2 different menus. One for outdoor dining and one for inside. The outdoor dining had the lobster roll, clam strips, burger, etc. The indoor menu didn't have the lobster roll, etc. I'd want to sit inside to look at all the cool decor but I like the outdoor menu better. Is the outdoor just bar or are there tables (we would have a 5 year old with us so can't sit at the bar to eat and the outdoor menu didn't list a kids menu section). I wonder if we can go inside to look around but then eat outside? Or can you get the outdoor menu inside? Prices seem the same as the restaurants here where we live in a tourist town in New England.
