021 Archivesfood-delivery wars never end, and now Amazon has a new play against Postmates and UberEats.

The Whole Foods owner just partnered with Olo, a restaurant software system used by many popular fast-casual eateries. The partnership means that most restaurants using the Olo system will now be available for delivery on Amazon Restaurants.

For the most part, these are the kinds of places you can usually only order from on Postmates: fast-casual restaurants that don't offer their own delivery. Think Chipotle, Applebee's, Sweetgreen, Shake Shack, Chili's, Red Robin, Noodles & Company, and Jamba Juice.

“We’re thrilled to work with Amazon to provide Olo’s base of restaurant customers with a new delivery sales channel that drives increased visibility,” Olo CEO Noah Glass said in a statement.

“Amazon’s obsession with providing great customer and restaurant experience supports the evolving expectations and behaviors of today’s consumer. We’re excited to connect more of Olo’s restaurant brands with Amazon Restaurants.”

Amazon Restaurants is available to Amazon Prime members. Besides competing with all the other delivery players, Chipotle delivery also gives Amazon yet another edge in its continued quest for every human on the planet to sign up for Prime.

“We are excited to leverage Olo’s digital ordering technology and continue rapidly growing our network of restaurants to give Amazon Prime members more options for fast delivery from their favorite brands,” Amazon Restaurants General Manager Gus Lopez said in a statement.

“This integration will enable Amazon Restaurants to onboard new restaurants with ease, as well as quickly add more new choices and delivery options for customers.”
