Dairy Freeze has graced the corner of St. Clair and Caledonia since before I can remember. I've been living in the area for 24 years (all of 'em, that's right) and it's barely changed at all. Sure, the old cigarette vending machine eventually became "for show only" (and then cleared out), and maybe they've changed a few lightbulbs or started carrying a few new drinks in the fridge, but that's about it.
While other childhood fave's eventually fall into the "it's not the same anymore" category, Dairy Freeze definitely makes 'em like they used to. Did I mention that you can completely customize your burger when it comes to toppings, etc? Even the Harvey's that always tried to hold its ground across the street eventually had to pack up and move out because it couldn't compete.
On a sidenote, I remember watching TV as a kid and seeing the Harvey's commercials promoting how they make your burger your way (customized) and remarking to my mom that they were trying to copy Dairy Freeze. Actually, I don't know the history, but it might even be true.
All that nostalgia aside, I should point out that they do way more than just burgers...as you'll note from all the signs and lights that scream "steak on a bun" outside. Go ahead and have the steak on a bun, the gyro (yeero), souvlaki on a pita or the banquet burger.
The next, and most important part is the SIDES. The fries are good...no shoelace laced-in-peanut-fat fries like at McD's. These are huge and by law must be eaten with the wooden mini-forks provided. If you are an onion ring fan though, screw the fries. Have the rings. They are not to be missed. I'll sometimes go in solely for these home-made goodies. Mmmm mmm AMAZING.
