I've been here a few times now and thought I'd write about my experience. I've had breakfast and lunch-type foods and both coffee and tea. No espresso drinks.
The food is ok. It's not amazing, it's not bad. It IS a little too expensive for the location of the cafe and the quality of the food. Basically, it's just solidly 'meh'. Haven't had a chicken from here though.
The coffee is decent. Not amazing, but good. People are complimenting the espresso drinks, which admittedly I haven't had yet. I'm confused about people being excited about a cafe opening though - i need to walk by three cafes on Gerrard that are reasonably nice to get to this one....if anything, there's too many. This one will be a great magnet for people going to the parks though.
What's to love about BG? The service is ALWAYS amazing. The people who work there are consistently delightful. Seriously. Basically all three stars are for service.
The decor is nice. It's kid-friendly without being annoying to adults. (Or at least me...I don't have kids but I don't hate them).
