Can't comment on the bread pudding specifically, hubby's always too full for dessert after one of their meals.
However, we just got back from a week at POFQ and had made 7 reservations for Olivia's (i have a lot of dietary restrictions and they are one of the best on site for me) and want to make sure you are aware of the complicated means to get between the 2 resorts. You can take either the boats or busses using disney springs as a transfer point but it can take upwards of 2 hours i suggest using lyft, less than 5 minutes and the cost was under $10 including tip!!!
