I can only review this venue in a late night, 3am, post clubbing capacity as it is the only time I have ever been. The reason I have a sort of fondness for the 24 hour diner is that it reminds of the the amazingness that is the US diner culture. I have memories of wonderful diners in every US state I have been in and the fact that there are some replicas in Toronto is great.
The first time I came here it was at about 3am and there was a line. In my opinion the bouncer has some sort of God complex typically seen in employees of hot nightclubs in Las Vegas, New York or Miami. I didn't feel such a complex was required in the queue manager of a diner in Toronto but he definitely had it. He let his friends or other randoms cut in ahead and was generally rather unfriendly. Perhaps this behaviour is more tolerable if one has had more drinks. The second time there was no line as I came around 4:30am and this method of entry was much more to my liking.
Both times I have had the grilled cheese with asiago and subbed in sweet potato fries. My other friends have ordered burgers and they are decent, generous portions. The first server I had was wonderful but my most recent was pretty inattentive, given that the place was less busy that usual. She also charged me a nasty extra $3 for the sweet potato fry sub.
So in conclusion, for a late night hangout to get a late night snack, sober up or continue hanging out this place hits the spot. It is also an excellent place to score a waiting taxi given that cabbies know most patrons leaving the venue at this time will be making their weary journey home.
I also heard Guy Fieri from Diners, Drive-Ins and Dives recently filmed an episode here and sampled the apple pie milkshake (a whole slice of apple pie, vanilla ice cream and milk). I don't know how that would go following a Saturday evening of drinking but I am intrigued none the less...
