Both have custom omelettes, but I think surfs up has a few extra options like pizzas and smoothies that I don't remember seeing at storytellers. Storytellers is fancier furniture and woody setting though. storytellers does not have photopass+ character photos, surfs up does with mickey. (free print with photopass plus, otherwise $30)
as far as I remember, surfs up had mickey waffles, pancakes, banana french toast, scrambled eggs, some type of mexican tortilla chip w/cheese and veg, bacon, sausage, pizza, various minimuffins, cinn bun, cereal, oatmeal, various fruit. I think storytellers had waffles, muffins, fruit, not sure about the rest. For some reason I remember surfs up better.
