Cake Bake Shop. The menu is bigger, the food is delicious & the portions are huge, so could be shared. Trattoria is loud, in 1 big room with lots of wood. CBS is several smaller rooms, quieter with lots of decor to look at. Our servers at Trattoria always seem rushed. CBS is a slower, more relaxed pace. My husband is a meat & potatoes guy. He never asks for Trattoria , but has asked for CBS the last 4 trips.
Have you looked at the menus? It’s always more about the menu for us. Also, CBS is on Open Table, many more options for times & party size reservations there than on the Disney site. However, they still require a credit card hold & have a 24 hour cancellation policy.
