Horrible service!!! Ordered take out via the app and when it said our food was ready we went in to pick up at the bar and the bartender told us to go to the window in the back. When we got to the window not a soul paid us any mind. They actually just argued over who's job it was to check us out and the girl that was supposed to bring us our food said she was done. We waited another almost 10mins with no1 even looking our direction. So we left. How hard is it to just bring someone their already prepared food and take a payment?
