Came here for brunch, and enjoyed the experience. Would give it a 5 but the wait time is incredibly long (45 minutes to an hour) and there is absolutely no room to wait. So unless you want to go for a walk around Point Breeze (which takes 2 minutes, lol) you are crammed in with other hungry brunch guests until your table is finally ready.
I ordered a bloody mary, the french toast and a side of potato gratin (part of the prix fixe menu). The french toast was delicious and perfectly cooked. I could have done without the gratin - it was somewhat bland, but the texture was good. My bloody mary was standard. Not good enough to get me to order a second one, but pleasing all the same.
In terms of vegetarian brunch options, there are a few, but I definitely recommend that french toast. I haven't been for dinner, but a quick glance at the menu tells me I have a few options (though not in the "Dinners" section). Can't fault them too much - it's not like Belgium is a very vegetarian-friendly place.
