Weber's is one of my favourite burger joints outside of Toronto. It kind of marks the half way point between Toronto and Algonquin Park. It's on Highway 11 in Orillia, Ontario. I've been going there since I was 2 or 3 (anytime we went up north to camp).
Anyways, in the 80's they acquired some CN train cars and retrofitted them to house their own meat-processing facility. They also acquired a few more cars which are now used as dining areas and restrooms.
Here's some recent photos I took on the way back from Algonquin Park. We got our food just in time because 3 full school buses pulled in shortly after we ordered. Though they have a grill man said to be able to flip up to 800 patties an hour.
As of 2009, Webers is reported to sell approximately 8000 hamburgers on a typically busy Friday.
