Fastfood:
When I lived in South Carolina, Hardy's used to make a burger called "Frisco Burger"... it was made with sour dough bread I believe... oh man what a f*ckin burger that was. I've seen them in NYC accross the street from MSG (Penn Station) on 5th ave in that Wendy's/Nathan's . I think they call it sour dough something or other.
Restaurant:
Don't remember the name of the restaurant, but it was on a pier in San Diego by the half pipes.. an old fashioned place with a red and white parlor theme inside, a 30 minute waiting list (well worth the wait!) and HOT waitresses. Anyone know the name of this place?
Hotel Krystal in Cancun makes a pretty damn good burger too.
Anyway, that was before I started hitting the gym regularly and watching what I eat. Now I eat chicken burgers on whole wheat bread. With the right spices, they're pretty damn good too.
