Our previous experience at Derf's had been a good one, and we had no reason to believe that this would be any different.
Boy, were we wrong.
I suspect the main problem was the wait staff, who just didn't seem interested at all. The waitress took forever to even notice we had sat down, took forever to get us anything to drink, and then got the drink order wrong. She eventually took our food order and we waited a good 30-40 minutes for it to be delivered. Two of the six orders were also wrong.
It might, at one time, have been good food, but by the time our burgers arrived mine was barely warm, the meat had the consistency of cardboard, and the cheese, which had once been melted was now a congealed rubbery mass. The bun may have once tasted good, but because of sitting so long, it had dried out and even I, the bread maven of the world, didn't want to deal with it.
Santa Barbara is a town loaded with wonderful places to eat, so I think it's fair to say that we will look elsewhere the next time we are in town and looking for a place to have brunch.
