Locals drive out to the ACK terminal just to eat here
Crosswinds sits inside Terminal 1 at Nantucket Memorial Airport and doubles as the island’s unofficial town diner. It’s past security by the gates, so you can keep an eye on Cape Air and JetBlue props while you eat. Price point runs about $$ by airport standards, but more like a standard Nantucket restaurant than a cheap mainland diner.
Breakfast is the move here: regulars call out the omelettes and full breakfast plates as the most consistent items, especially on 6–9 a.m. flights. Portions are “good-sized for an airport” but just normal for Nantucket, so a single plate usually covers you for a BOS hop or a longer layover. Coffee refills come fast when it’s quiet, slower when multiple departures hit at once.
The menu runs basic American diner: burgers, sandwiches, fries, and a few full entrées, all in the mid-teens to low-$20s range. Most crew and staff reviews say the burger and simple sandwiches are the safest bets once the kitchen gets busy. If you feel like gambling less, skip the more elaborate specials when three or four flights are boarding within 45 minutes.
There’s a full bar with Nantucket beers on tap, which is rare for a tiny regional field like ACK. A pint before a Cape Air C402 leg runs about what you’d pay in town, not what you’d pay in Hyannis. The bar side can get loud when delays stack up, so people catching soft-boarding prop flights tend to grab tables away from the taps to hear announcements.
Watch out for summer weekend crunch: service slows sharply when a bank of flights hits, and waits for cooked food can pass 25–30 minutes. Prices also sting compared with mainland diners, even if they line up with downtown Nantucket. Tip: on peak July and August days, eat here 60–90 minutes before your scheduled departure, then clear security once you’re fed.
