Fantastic atmosphere, delicious food, subpar service and poor management.

I've been to this location 3 times now. The first time I was treated very poorly by my waiter who disrespected me, ignored me when I flagged him down and prevented me from ordering beer 30 minutes before bar close. The second time I was treated fabulously by a bartender who went out of his way to make our experience exceptional and told many stories to enliven the food and the location to us. I have come here for a third time and was told I could order unlimited samples of beer 3 at a time. Then after I picked my first 3 they told me the max was 5 so I only had 2 other options before I had to pay for them. I said I was very willing to pay but after my next 2 samples they cut me off of samples entirely. My water was delivered with a very bitter chemical tasting film on the glass that made me gag. The waitress forgot our sauce with our sweet potato fries appetizer. At the end of our experience the manager was very condescending and abrasive and made my girlfriend and I feel extremely uncomfortable and unwelcome here. The food has been absolutely top notch every time I've come here. It always looks beautiful and tastes amazing. I highly reccomend the truffle fries with spicy aioli, the unami burger and any of the tacos. If the service at this location was better I would be a regular as I live close by. But I do not like being jerked around and ignored by staff or having my beverages delivered in dirty chemical coated glasses and having items I ordered forgotten. Being treated with such brash arrogance by the manager on duty made me decide to not return to the Cedar Rapids 30Hop in the near future. She was so cold and rude to us and I refuse to tolerate that level of abrasive behavior from an establishment I am paying to visit. This beautiful location is tarnished by the lackluster presentation of some undoubtedly magnificent product. So much potential here.
