My family and I are coming to NYC this weekend, and my son wants some authentic NY pizza. We're staying near Rockefeller Center. I heard about Two Boots in Grand Central, but heard it wasn't "authentic". Any suggestions? My daughter is also looking for the best cheesecake (and I'll be happy with both or either). We are on a bit of a budget, but I don't think pizza should break the bank). Thanks for any info!
