Grubhub, which also owns Seamless, is the biggest player among food-delivery services. It processes nearly 500,000 orders daily, and its more than 22 million active diners can order from more than 155,000 takeout restaurants in over 3,200 U.S. cities plus London. Search by what you’re craving — the most popular dishes include cheese pizza, hamburgers and tuna rolls — and if you’re deciding between restaurants, peep the user-generated ratings and reviews. Grubhub Perks offers exclusive discounts and deals and you can earn restaurant loyalty rewards to redeem from the likes of Just Salad. Users can do good while they dine through initiatives such as RestaurantHER, in which diners can explore a map of women-led restaurants to support, and "Donate the Change," where diners can round up the change from orders to benefit No Kid Hungry. Since 2018, diners have donated more than $10 million, equivalent to 100 million meals.

Caviar is like the boutique hotel of food delivery apps, eschewing chains in favor of partnering with local and independent restaurants (some of whom are exclusive to Caviar) in 28 cities, including Boston, Chicago, Dallas-Fort Worth, Los Angeles and Orange County, the greater New York City area, Philadelphia, Portland (Oregon), Richmond (Virginia), the San Francisco Bay area, Sacramento, San Diego, Seattle and the Washington, D.C. area. Top restaurants include Bareburger (all-natural burgers and shakes), Made Nice (fast-casual seasonal dishes from the Eleven Madison Park team), RPM Italian and Souvla (spit-fired meats; pictured). Within your city, you can search restaurants by categories such as cuisine, or browse via quick links including women-powered, trending, vegan or healthy. Speaking of healthy, Caviar also has an in-house nutritionist who often curates recommendations for a range of health interests and diets. And whether you ordered RPM Italian’s bucatini or a Paleo-friendly dinner, you can track your order in real-time via GPS tracking. For your office crew, Caviar for Companies allows groups and individuals to order restaurant catering or lunch for your whole team from a company account.

Postmates bills itself as "an insanely reliable on-demand 'anything' network," offering delivery from restaurants and stores alike, so you can order a bottle of pinot grigio from your local wine shop to go with green coconut curry from your fave Thai takeout joint. Postmates operates in 3,500 cities in the U.S.; offers goods from more than 25,000 merchants; and makes 5 million deliveries per month. Besides tapping into the best of each city’s local food scene — hello, pizza from Pizzeria Delfina in San Francisco (pictured) — you can also snag delivery from fan-favorite chains such as Red Lobster, Applebee’s, iHop, even Pinkberry. And if you’re catching a game at Yankee Stadium or Dodger Stadium, Postmates will deliver hot dogs to your seat. Postmates also counts celebrity fans: Actor Seth Rogen and his wife have spent $21,320 on 227 orders in nine cities, including a splurge sushi dinner from Sugarfish totaling $276 (as reported by E! News).

ChowNow partners directly with more than 12,000 independent restaurants across the U.S. and Canada to offer takeout (and in some cases delivery) to its 6.8 million active diners and is projected to process $725 million in orders this year. By partnering with ChowNow, restaurants avoid racking up the commission fees charged by many third-party delivery apps that can cause them to lose money on orders. For the diner, this means supporting their fave mom-and-pop breakfast joints, stone-oven pizza place (The Butcher’s Daughter in L.A.; pictured) or the locally beloved plant-based burger spot (looking at you Pirate’s Bone in Kansas City) in a way that ensures they’ll be around for the long-haul.
