Best burger I've had was the Blue Cheese Burger from GBK (
Gourmet Burger Kitchen)
It's not really fast food though.
I like a big fat meaty burger, where I can taste the beef.
At McD's I'll eat a 1/4 pounder to get a fix, but it's too salty and nowehere near thick enough.
Oh that reminds me, I have some McD's tray inserts I wanted to ask about. I'll make a new thread.
