I'm going to SummerStage next week for a show that starts early, 6:30 I think, and wanted to grab some dinner first. I'm thinking that I could use the early hour to my advantage, and grab a table somewhere that would usually be packed. Money not a big factor, but I can't stay really long. Would arrive around 5 and need to leave by 6:15 or so. East side preferable, but since I work downtown it can be anywhere south of the park. Would I be able to breeze in and out of Gramercy Tavern in that span of time?
