Craving melty cheese curds and gravy over fries at 4:30 AM? Don't wanna wait in line at Schwartz's? Cross over to the Main! They more menu items and better hours!
I'm not going to lie, it is hard to beat Schwartz's fatty smoked meat, but The Main has a pretty excellent Ruben, charming fried onion petals, and some pretty decent poutine topped with smoked meat. The service is friendly, food comes out pretty fast, and leaves you ready to to pass out into a food coma.
They do charge you to share food, which I'm not psyched about when it is just myself and a friend in an otherwise empty restaurant (FWIW I can't remember if I looked for the surcharge or not), and the fries are nothing to write home about (though I don't think I've ever had fries with poutine that were).
