The Famous Cosmos is described as an old school diner with a warm, nostalgic counter vibe and a small town feel that makes guests want to linger. The atmosphere is casual and lively, with stools at the bar, friendly chatter, and a sense of community that makes regulars and first-timers feel welcome. The menu earns strong praise for generous portions and solid flavors, especially the Mish Mash, popular breakfast staples, and comforting burgers and potatoes, all at very good value. Coffee is consistently highlighted as top notch, and service is noted as attentive and efficient even when seating is limited. While space can be tight and the setup simple, patrons appreciate the unpretentious, no frills ambiance and the quick, tasty fare that brings them back year after year, underscoring Cosmos as a staple breakfast and diner spot in NDG.
I was in Montreal back in November for a Paul McCartney concert, & a good friend of mine back home (who is Montreal-born & raised) told me that I should absolutely have breakfast here at some point during my week-long visit. He had recommended having the Mish Mash, so that's what I ordered.... It was so good! 🥰
The coffee I also had was top notch, & chatting with the staff & the others seated at the counter gave Cosmos a kind of small-town blast from the past feeling & ambiance.
I will definitely return here whenever I visit Montreal again! 🙂
The food & service were impeccable. I was a little unsure when walking in, but my friend assured me it was worth sitting on bar stools & it definitely was

If Anthony is cooking you cannot go wrong, he makes incredible burgers, his potatoes always hit, he has not missed once. I love this place, it's an NDG gem!!
Arrived here & had to wait 20 minutes for a stool to open up, finally when a seat became available. This older woman came in & said that her & her husband were waiting before me.
She was outside smoking & kept coming in & out of the place, I didn't see her husband anywhere, but nonetheless, I got out out of the way & let her sit
Waited another 15 minutes for a seat & then finally became available, after sitting down for another 20 minutes I was finally asked if I had been served yet. I told them no, & the man was very apologetic noticing I had been waiting a long time to order & sitting patiently.
I was quickly offered coffee & the gentleman took my order right away, the food was made hot & ready within minutes & was very flavourful & tasted amazing again the coffee was top shelf & tasted really good.
I ordered a BLT with a side of hash browns (mashed spuds with onions fried on a flat grill)
This place has to be the best bang for your buck in the city.
The atmosphere is very jovial, the food is really good. The price again is fantastic & once more, I really enjoyed the coffee.
If there was anything to complain about it was the stools or a little hard to sit on, but because the food tastes so good & you eat so fast you're out of there so quickly you don't even notice.
I'll definitely recommend my friends & family to come here again.
