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.
