Lead With the Oklahoma Smash Burger
Start with the onion-smashed signature to understand how Big Bam uses griddle crust, softened onions and sauce to give a familiar burger a more deliberate savoury shape.

The Oklahoma smash burger is a test of nerve as much as technique: raw onions pressed hard into the beef the moment it hits the flat-top, the patty left alone long enough to build a lacquered, craggy crust before it's scraped up and dressed. At Big Bam Burger, that single move sits at the centre of everything the kitchen does. Two thin patties, thinly sliced onions steaming and softening beneath them, and a house sauce the kitchen simply calls Bam come together into the restaurant's signature — a familiar burger reshaped for deep, griddled, savoury edges rather than sheer height.
The burgers build outward from there. The namesake Big Bam anchors the board, with a Double Mac Daddy and a straightforward double cheeseburger for anyone chasing more of the same. When the beef starts to feel too familiar, the kitchen's other pillar is chicken: a Nashville hot chicken sandwich, buttermilk-brined and fried crisp, carries a spicy finish that stays focused inside the bun, while a milder O.G. chicken sandwich and a basket of crispy chicken bites give the heat-averse and the sharing table somewhere to land.
The sides are treated as more than an obligation. Cheeseburger fries arrive loaded with seasoned beef, cheese, pickles and sauce, covering much of the same ground as a full burger and making the most sense split across a table. A proper Canadian poutine comes under cheese curds and gravy; there are mac and cheese bites, onion rings, and Nashville hot fries for anyone who wants the spice without committing to the sandwich. Dessert leans deliberately playful — mini churros, a Cookie Monster milkshake, and a rotation of seasonal shakes such as butter pecan and pumpkin spice that turn the end of a meal into its own small event.
What all of this reveals is a kitchen willing to be particular about casual food. The plant-based smash burger isn't an afterthought slid onto the same griddle as everything else — it's cooked on a dedicated vegetarian-only flat-top, a small operational decision that quietly accounts for the person who orders it. The same instinct runs through the burger-first identity. Rather than a sprawling lineup that tries to be all things, the menu commits to one clear signature and lets the Nashville chicken and the loaded sides give a table somewhere else to go, so a mixed group can assemble several different kinds of indulgent meal from one order without anyone stuck with a consolation plate.
That flexibility is the practical heart of the operation. Big Bam opened in 2024 and runs dine-in, pickup and delivery off the same menu, so its Bronte Village storefront on Lakeshore Road West works as easily for a tray carried home as for a table of kids and parents sorting out who wants what. A Wednesday kids promotion gives families a specific reason to pick the night, and the spread of burgers, chicken, loaded fries and milkshakes leaves room for appetites that never quite line up. Bronte Village itself, a short walk up from the harbour, is the kind of lakeside pocket where a dependable burger counter picks up steady weeknight traffic. The room is casual and built for speed — order at the counter, sit for a while, or take the whole thing to go.
None of this is trying to reinvent the burger, and that restraint is the point. Big Bam is a neighbourhood shop that picked a handful of things worth doing carefully — the onion-smashed patty, the crisp hot chicken, a side that eats like a second dinner — and built an easy, generous meal around them. On a stretch of Lakeshore Road West where a family can land on a Wednesday night or grab a late Friday order on the way home, that focus is what a neighbourhood quietly builds a habit around.
The Oklahoma Smash Burger uses onions beneath smashed patties and a house sauce to give the menu a specific centre rather than a generic burger lineup.
Nashville hot chicken, loaded fries, poutine, mac and cheese bites, ice cream and milkshakes let a group build several different kinds of indulgent meal.
Dine-in, pickup and delivery are all available, while the Wednesday kids promotion and plant-based burger help mixed groups find a workable plan.
