Few things are more sentimentally American than a Billy Joel concert, but a baseball stadium might be one of them. Which makes Nationals Park the perfect venue for the beloved singer-songwriter and newly-minted Gershwin Prize-winner's Saturday concert. If you're planning on singing along to "Scenes from an Italian Restaurant" this weekend, here's what to know before you go:

In the first of four ballpark stops this tour, Joel performed to a sold-out crowd at the home of the Boston Red Sox, following the lead of past performers such as Paul McCartney and Bruce Springsteen.

Can I still get a ticket?

The concert is sold out through tickets.com, but spots are still available on StubHub starting at $79. Avoid buying tickets from scalpers outside the stadium though — it's an arrestable offense in D.C.

What time will the stadium gates open? 

6 p.m.

How should I get there?

Starting at 4 p.m. Nationals Park offers parking at nine different lots near the stadium, but it'll cost you $47.50 per car (almost as much as the concert ticket itself). Public transportation is your cheapest option: The Navy Yard stop on the Green Line is one block from the stadium, and the Union Station-Navy Yard Circulator will also drop you off within a block of the park. Ticket holders for on-field spots can arrive to pick up their wristbands as early as 4 p.m., but the concert itself doesn't begin until 8.

What about the weather?

The forecast for Saturday is characteristic for D.C. in July: hot and humid. So don't wear your leather jacket, no matter how much you want to recreate the cover of Glass Houses.

Where should I get dinner and drinks before hand?

It's been five years since Billy Joel last sang at Nationals Park, and he'd be impressed by the array of dinner options that have popped up in the neighborhood since then. Bluejacket Brewery is good for handcrafted beer, but for a full meal your best option is, perhaps fittingly, the Italian Osteria Morini on Water Street. For something quicker, Justin's Cafe is a reliable bet for pizzas and sandwiches. MORE: Where to eat and drink near Nationals Park.

What can I bring?

Not a "bottle of red" and a "bottle of white," that's for sure. Nationals Park prohibits all outside food and drink, with the exception of one clear, factory-sealed plastic water bottle per person. Other banned items include beach balls, laser pointers, record covers (in case you were hoping to get an LP signed) and signs of any kind. 

Can I buy food at the stadium?

Update: According to a Nationals spokesperson, most of the ballpark’s regular concessionaires will be operating Saturday. Shake Shack and Ben's Chili Bowl will also be open. Vendors located on the Miller Lite Scoreboard Walk (not including Shake Shack) will be closed.
