Dole whip float or pineapple upside down cake. For something not so sweet and shareable I like the nachos at Pecos Bill, plus you can add things from the toppings bar. I know a lot of people also like the fruit and Nutella waffle from Sleepy Hollow. I haven’t had them yet, but I think that the Friar’s nook still has loaded tater tots, which might be another good shareable option.
Pretzel with cheese, churro, Pecos bills has tortilla chips as a side which you could load up at the toppings bar. You could also go somewhere that has entrees you could share (eg. I haven’t had them but I see Columbia Harbour House has platters that sound shareable. DD and I have shared 8 nugget meals at AoA and it was too much food for the two of us).
