The restaurant is incredibly small (as are most of the restaurants located on Ellsworth Street in the city's Shadyside neighborhood) so I would strongly recommend making reservations for dinner. They also serve lunch so you might have better luck then with just being able to stop in. They do have a decent size bar area and there were a couple of people who were dining there.
As it is a French restaurant, their wine selections are quite extensive but they do offer about five beer selections, all Belgian except the French beer Kronenbourg 1664 which D actually had while we were in Paris last year.
To start, D ordered the soupe a l'oignon (traditional French onion soup) for $8. The menu didn't identify the type of cheese used but it tasted like Gruyère. I had a couple of spoonfuls and it was excellent.
I'm a huge cheese lover and was excited to try the B33 tarts (warm brie, goat cheese, and caramelized onion tarts), but was extremely disappointed when told "they were all out of tarts." I found this beyond odd, seeing as how we were literally the first people in the restaurant when they opened for dinner and the fact that it was a Saturday night which I would think is the busiest night of the week for them. I ended up just ordering a side of pommes frites (fries) for $6. They were very tasty and almost as good as the ones we had in Brugge, Belgium from the fry stands that are at the base of the belltower.
D ordered the coq au vin (traditional French chicken dish with onions, bacon, mushrooms and roasted potatoes in a red wine sauce) for his main entree. He debated between that and the boeuf bourguignon (braised beef with garlic, onions, carrots, bacon and mushrooms in a red wine sauce).
