Chastity at the improv show was absolutely amazing! She kept the energy up, was super attentive, and somehow managed to be both hilarious and professional at the same time. Orders were quick, drinks were always excellent, and she added to the fun of the night instead of just serving it. The nachos with excellent. She really helped make the whole experience memorable. Give her a raise!

EAT & DRINK SOMEWHERE ELSE BEFORE. 3rd time here. Shows are great and always in need of a good laugh. Drinks take forever to arrive since everyone orders when the doors open. Food was not up to quality. wine glass dirty, moscow mule with no mint or lime. Garlic fries had garlic thrown only on top and bottom filled with oil..Never got mu guac or avocado for my nacbos. Nachos needed more cheese.
