The pizza cheese was melted but was dry and burned. We got 3 slices and all 3 came came out different levels of burnt. The staff was outside taking orders and when I had questions about the quick service they were confused and made me feel uncomfortable for even asking. Then I asked for red pepper flakes and you would swear I had 10 heads. Is that not normal for pizza? Never again. Avoid!!!
