Caledon Burger Co. occupies an old brick house formerly home to a gourmet food store. There is quite a bit of seating inside as well as several red picnic tables outside. The place was well staffed and everybody was generally friendly.
We had the regular quarter pounder burgers with a side of fries and onion rings. The burgers were quite juicy...you will definitely get messy! I second Charlie K's comments about the chipotle sauce, it was tasty! You get to choose your own burger toppings à la Harvey's...the toppings are your basic standards except for the onions: they offer white, red and later on I heard a customer ask for sautéed. I wish I knew! They must store the sautéed onions somewhere else. The fries are thick cut and taste homemade. The onion rings were crispy and quite good.
Price-wise, it was a little more expensive then I expected for a place outside the city but it's along the same lines as places like Gourmet Burger Co.
