We still like the burgers at B&C (but we don't love and often get the roast beef sandwich to split now). We don't eat at Sci Fi anymore as the last burger I had there had a foreign object on it and I can't bring myself to go back (neither can any of our family members). But, when I really want a great burger, we jump in the car and drive over to Margarittaville for a Cheese Burger in Paradise, now that's a burger!!
I agree, I don't like the new buns in WDW, so will continue to look for a great burger on property.
