Best greasy spoon, Cosmos or Moe's corner snack bar on the corner of Lambert-closse and de Maisonneuve, right across from the old forum. It's open 24 hours and if you're not in the mood for eggs, get a Big Ed burger and strawberry milkshake (drool!). Best breakfast potatoes in the city belong to Le Petit Pistou on the corner of Mount Royal and de la Roche. If you want meat for breakfast and are into NDG, go to Mesquite. This place does some great southern style BBQ dishes for lunch and dinner (pulled-pork, brisket, etc.) Their breakfasts include some of the same stuff and are reasonably priced. For fun decor, I love Bagel's etc. Their blintz's are great. And there's always Chez Claudette if you need a poutine to accompany your eggs. Lastly, Sala Rossa does the best Huevos Rancheros! Make sure you get it with a side of chorizo sausage. I think they only do brunch on Sunday though.
