This is my go-to place for brunch on Sundays, particularly if you have friends that have all sorts of food sensitivities.
The Beet is easy to walk past - the front entrance there is a TD ATM (from what I can tell, and from what people say, it used to be a TD bank?).
The food - every time I go with people here, I always seem to order the wrong things, because everyone else at the table is often oooohing and ahing at how good their food is! Their vegan mac and cheese is no replacement for the real thing - the cheese tastes a little bit strange. The quinoa/mushroom burger is actually good - it's the first veggie burger patty that I've had that hasn't crumbled to pieces, and the meat simulation is pretty convincing. My fiance constantly orders the huevos rancheros and swears by them (plus the blue cheese walnut sausage). For brunch for 2 people, it often works out to be around $40-$50, which seems to be slightly pricey.
As far as I know - no reservations, but the wait is never too long (and they typically call you so you can wander about outside.)
Also note: because the kitchen is in the same area as the dining area, all of your clothes smell like cooking smells after you leave.
I like the local art that they put up on the walls as well.
