An eatery is simply a place where people can buy and eat food. The word covers everything from a small sandwich shop to a fancy restaurant, from a diner serving breakfast all day to a food stall at the state fair.

You might see a sign that says “Local Eatery” on a neighborhood café, or hear someone say “Let's find an eatery” when they're hungry but haven't decided on a specific place yet. The word sounds casual and friendly, less formal than saying “dining establishment” but more interesting than just saying “restaurant.”

Eatery is especially useful when you're talking about a place that doesn't quite fit the usual categories. A food truck, a cafeteria, a burger joint, a noodle bar: they're all eateries. The word focuses on the main point, which is that you can get something to eat there, without worrying about whether it's fancy or casual, big or small.
