We stopped by for a quick dinner on Sat night and it is very easy to spot as it is located west of the Spadina and Queen intersection.
Decor: Loved the full wall mural and seating. Menu looked like it was written in chalk on the top of the wall.
Food: We ordered 2 hotdogs, fries and mini-donuts (I was surprised they had donuts!). First, the 2 hotdogs we tried were: Fancy Francine and Kimchi Dog. Fancy Francine bit - it had a whole egg sunny side up with bacon and hollandaise sauce underneath. Tough to eat but tasty. The kimchi dog was a korean twist with kimchi, seaweed and mayo. Similarly, tough to eat but tasty. The buns for both were soft and fresh. Flavour-wise, the toppings were great but I found the hotdogs to be a bit tough to bite through - perhaps the it could have been cut a bit before serving. Fries were great. But by far the best and perhaps most surprising was the mini-donuts - we ordered a 6-pack of the nutella glazed with crush biscotti - wow - this was amazing!!! Donuts were made on the spot so they were warm and soft. Combined with the nutella - the whole thing melted in your mouth!
So - hotdogs were a bit mixed (Kraft Dog has better flavour) but the donuts were the best!
