I have yet to encounter awful food at Nats Park (though, I've only been to four games). I've done, "slice down the line," "Ben's Chili Bowl," "Five Guys" and "Nats Dogs" and each of them I found to be superior to any other park I've been to (OPACY, Fenway, Shea, Yankee and The Vet). However, bring your credit card with a high limit.
