This is the place to go to if you want to skip dinner and go straight to desert. Demetres will most definitely fill you up (I hope). The portions are HUGE, especially for their waffles and crepes. So bring someone with you to share a plate.
I recommend everything on the menu except for the ice cream sandwiches. The cookie was SO hard and eating it was messy. The waffles/crepes are so warm when it's ready and it tastes amazing with the cold ice cream. The ice cream is very rich too.
The staff is very nice and you get you food quickly. One time on a busy night, the waitress didn't come for 15 minutes when we were ready to order. I think she forgot about us, so we left. I don't think much of this because this has happened once out of the 1000 times I've been here. The prices are good since you get a TON of desert.
It's only a few minutes walk away from Royal York station. If you're driving, you'll have to park on the side walk or behind the cafe, which you have to pay for obviously.
