Kosmos Smash - Best Burger in London, Ontario

(121 reviews)

The Kosmos Smash is built the way a comfort food burger should be - seasoned beef smashed on the grill with onions, topped with cheddar cheese, lettuce, pickles, and our kosmos mac sauce. It's a straightforward, satisfying burger made fresh for every order at Kosmos Eatery.

Kosmos Smash at Kosmos Eatery in London, Ontario - smashed beef patty with onions, cheddar, lettuce, pickles, and kosmos mac sauce

About Our Kosmos Smash

At Kosmos Eatery, the Kosmos Smash is a staple of our American comfort food menu. Every patty is smashed fresh on the grill with onions and stacked with cheddar cheese, lettuce, pickles, and our kosmos mac sauce.

It's a favorite for lunch, dinner, and everything in between for guests across London, Ontario looking for a satisfying, no-fuss burger done right.

Why Our Kosmos Smash Stands Out

We never pre-cook or hold our patties - every burger is smashed fresh once you order, so it arrives hot, juicy, and exactly the way a comfort food burger should taste.
