I'm not sure if the bun was slightly toasted, or stale, but it was cold. Pat's also dishes out some of the worst french fries I have experienced, consitently undercooked and soggy.
Breakfast food is alot better, but still nothing special.
Years ago, this was a lovely diner, then it was butchered in two remodelings. A bit of stainless remains on the outside, but the interior has been entirely gutted.
