Review for MGM National Harbor Review For Zizi's Pizza Google User Jul 6 '18 at 1:23 I was at MGM for my birthday weekend and I am sure I ate here at least 4 times. Not only was the pizza outstanding, the crews that were working June 30 to July 2nd were so in sync with one another and handled a massive line each night LIKE CHAMPS!!!! KUDOS!!!
