Colossally slow service at the Biergarten outside of Crescent Ballroom recently. Waited for 15 minutes (in a line with maybe five people ahead...) to have my order taken, only to be told that they were out of veggie burgers and sweet potato fries. I ordered some regular fries instead, and waited 20 minutes for those.
Owners: put up a post-it note on the menu if you run out of something. You should also serve fewer options - the slowest part of your operation is your cooks being confused on what they were making for literally every order I watched you take for the ~40 minutes I stood there.
