Stop into Thompson’s Point en route to the airport, where the kitchen of this revered Portland brewery has a robust dinner and lunch menu. The selection runs the gamut from veggie burgers and salads to burgers, tacos, and wings. Pair your meal with a pour from one of the brewery’s 20 taps.

A family-run institution since 1965, Tony’s makes its popular, dense cake doughnuts daily. Other styles are also worth trying, from Maine whoopie pies to enormous eclairs (more like elongated Boston cream doughnuts). The bakery opens at 5 a.m., perfect for an early departure.

With grab-and-go options like baked ziti or cheese pazzo bread (basically cheese pizza with the sauce on the side), plus plenty of made-to-order pizzas and wraps, Amato’s has long been a good choice for especially hungry travelers. Looking for an iconic Maine sandwich that doesn’t involve lobster? Amato’s is home of the Real Italian, a classic sub with ham, cheese, and all the veggies.

Huong Le’s first pho restaurant, which closed years ago, was well loved. Her second restaurant, with help in the kitchen from her daughter, has rekindled that passion. A hearty bowl of noodle soup will get flyers through a connecting flight or two, while the rest of the menu includes Vietnamese classics like banh mi, vermicelli bowls, and curries.

A neighborhood institution founded in 1965, Pizza Villa serves up great pies in only one size (10-inch). Order at the counter and enjoy at a booth, or take it over to the connected old-school bar where the beer is ice cold.

For lunch or dinner, chef/owner Jay Villani’s barbecue joint offers expertly smoked brisket, ribs, chopped pork, pies, and more. Order at the counter for takeout or dining in, or belly up to the bar for one of the 16 local beers offered on tap.

This modern Portland landmark opens at 6:30 a.m. A Maine potato doughnut (the dark chocolate sea salt is world class) and a cup of Wicked Joe coffee can make an early departure much more bearable. There are even gluten-free options.

The empanadas and smoothies from this Central American cafe travel well, so stop into Quiero for a quick meal. In addition to savory classics, the empanadas menu includes sweet variations like pineapple with ham and cheese, or arequipe (dulce de leche) and cheese, plus vegetarian choices. You can also enjoy larger plates like burritos or specialty items like Colombian hot dogs.
