I live in the neighbourhood and go to that place a lot for brunch. There is usually a line up on weekends, although we've never waited more than 30 min for two people - which, based on the food and service, makes it totally worth it.
The food can be quite overpriced if you get their fixed meals. I usually get the plain Belgium waffle ($7) and then choose add-ons from the side menu, which is the cheaper and more flexible option.
Besides the fact that they're known for their waffles, I love their scrambled eggs and coffee!
Atmosphere and service is really good. Overall, it's a really cute little brunch place in this area, that's nice to visit every once in a while!
