After toying with shorter hours, this Dundas West institution is back to serving diner classics, every hour of the day. Whether you crave a loaded milkshake for breakfast, a towering club sandwich at lunch or disco fries when the city is sleeping, you'll find it all here.

There's no such thing as a night off at this 24-hour Scarborough spot that's also open 365 days a year. No matter what time the cravings hit, this is the place to feast on fresh seafood, dim sum, hot pot and other Chinese staples in the company of other perpetually-hungry diners.

With a menu that includes all-day breakfast, sandwiches, pastas and more, there are plenty of temptations offered around the clock at this family-friendly Yonge & Bloor café. Inspired by flavours of the world, dishes jump from spring rolls and lasagna to huevos rancheros and classic poutine.

Few things are as fortifying in the dead of night as a fiery bowl of kam ja tang. Regulars to this North York Korean spot also make use of table-top grills to sizzle meats — from sliced sirloin to short ribs — to perfection.

A go-to Scarborough spot for sizzling steaks and charbroiled burgers, this diner does brisk business, all day and night. When the signature 16-ounce T-bone is too much of a challenge, burgers, souvlaki, and sandwiches — with peameal, chicken, sausage, and more — are a decent alternative.

Join the colourful mix of characters frequenting this Chinatown spot for sustenance every hour of the day. Few breakfasts are as invigorating as one made up of aromatic broth teeming with beef brisket, tendon, tripe, jumbles of herbs and snappy tangles of noodles

Snack on jjin mandu as you peruse the lengthy menu at this North York staple. Depending on your level of inebriation, table-cooked meals are either a brilliant, or atrocious, idea.

No matter the hour, sweet and savoury teeth find something to sate at this Castlefield Design District bakery and café. Saucy veal sandwich, fat calzone or cream-filled cannoli? Here you can dive into whatever the day, and the hour, demands.
