Found this gem on skip and had to try it. I was blown away! It was easily the best breakfast I have had in such a long time! The comet ( peanut butter and jam stuffed french toast, dipped in pancake batter then deep fried) is a must try, amazing take on an old classic. Corned beef hash is also amazing. So many amazing things to say about this place, but you should see for yourself!! Can't wait to order again and hopefully dine-in very shortly.

I liked this diner a lot! The interior was bright and colourful, with pictures of classic stars and vintage records adorning the walls. Even the fixtures gave the place a nice retro feel. The place is of a good size, but it wasn't crowded around 2pm on Saturday. The menu is huge, with so many options that you'll be inclined to come back to try something new. This visit we tried the breakfast poutine and breakfast lasagna as they sounded unique. Both were delicious and very filling, and were of good value considering the price. Overall, I'm looking forward to visiting again. This is a place you'd want to go whether you're looking for a nice nostalgic joint or hearty hangover food (I won't tell you which reason I came here for).
