My husband and I each had a burger, which was cooked to order, and the taste was fine. The gluten-free bun was hard, and a knife was used to try and slice thru it. I would recommend B. O. using a different provider for those. We have been to other restaurants that use gf buns that are soft and tasty, so we know the availability is out there. So, if you're gluten-free and want a burger here, just order it without a bun.
Being dairy-free, I was excited to try the vegan shake option. I had chocolate, but the taste was just to the right of vanilla. It filled the bill but wasn't outstanding.
Our waiter did a fine job. The place was ultra busy, so we didn't see a lot of him.
