Review for MGM National Harbor Review For Zizi's Pizza Google User Dec 7 '17 at 21:39 Very poor service...I'm sure this is a good spot, but during a non-busy time, you at least expect the basics. Refills on your drink, asking how your food is, extra parmesan/red pepper, but did not receive any of that from my server (bartender) whose duties instead were completed by nice waitress. It was obvious this was not the waitress's job. Needless to say she got the tip ;) View full site to comment or like
