20 Spots Serving the Best Hangover Cures in Montreal

"Even though the Koulakis family sold their beloved NDG greasy spoon joint in 2020 after more than five decades in business, the new owner has promised not to change a thing. That’s good news for hangovers everywhere, as you can never underestimate the power of a good, greasy protein-packed breakfast chocked with eggs and sausage to get your day-after going." - JP Karwacki, Joel Balsam

Where to Go for a Brilliant Weekday Breakfast in Montreal

"Legendary NDG diner Cosmos, founded by the late Tony “Man of Grease” Koulakis, opens Wednesday to Sunday at 7 a.m. for pulse-quickening hangover breakfasts. Although the Koulakis family sold the diner in 2020, the new owners haven’t veered far from Cosmos’ menu, on which potatoes (in the form of delightfully crispy hash browns) are king." - Valerie Silva, Holly Tousignant

Nikos Koulakis, Former Owner of Famous Montreal Diner Cosmos, Died Last Week | Eater Montreal

"I remember a tiny family greasy‑spoon diner in NDG that has been a beloved Sherbrooke Street haunt since it was founded in 1967. Run for decades by the Koulakis family, it became known for Nikos frying eggs, making hefty mish‑mash omelets, perfecting the hash brown and presiding over the flattop grill behind a counter of just eight stools; he greeted everyone with a smile and helped make the place famously welcoming. The enduring signature Creation Sandwich — stacked with a fried egg, bacon, salami, cheese, lettuce and tomato between toast — was invented there by Nikos and is still served today. The diner’s story and family legacy were even chronicled in the 2000 documentary Man of Grease; the Koulakis siblings ran the tiny restaurant until selling it in 2020 to David Minicucci after their father Tony’s death in 2013." - Valerie Silva

Some of La Poutine Week’s Most Intriguing Creations in Montreal | Eater Montreal

"At the Famous Cosmos I appreciate that the Cosmolio showcases their signature potatoes — boiled then mashed on a flattop into a hash-brown with bits of almost caramelized char — topped with bacon, sausage and a fried egg (a nod to the iconic Mish-Mash Omelette) and finished with cheese curds and gravy for a breakfast-leaning poutine." - Valerie Silva

Beautys Sends Legal Threat to Bagel Etc Over Mish-Mash | Eater Montreal

"At Cosmos in NDG, I noted their longtime Mish‑Mash is a different combination—tomato, cheese, bacon, onion, ham, salami, and sausage—but Beautys’ owners maintain that the name is theirs regardless of recipe. Cosmos received a cease-and-desist letter as well but has not made a public comment on the matter." - Tim Forster
