Zak's Diner

The best milk-shakes are found at Zak's, a 24-hour diner in the Byward Market. They're really good, made with ice-cream, and for the $6.99 they cost you get a large glass full plus the shaker with what didn't fit in the glass. Other dishes are quite good, with a "more calories for your money" attitude (as illustrated by the massive amount of milkshake served), which is nicely honest about fast food; however it may seem a bit expensive as the burgers start at $14.49 and if you add on the paid extras you can easily get in excess of $19. Late on week-end nights (2-3AM), it's packed as people go for their after-bar poutine. There are two additional locations on Elgin Street and in Kanata.
