Amazon.com Inc. is shuttering its restaurant delivery service Amazon Restaurants in the U.S., putting an end to a four-year experiment that sought to compete with the likes of Grubhub and Uber Eats but failed to gain much traction.

Amazon AMZN, +0.66% said it would discontinue the service on June 24 and that the small number of employees who made up the division have found new roles within the company or will be provided assistance with finding new positions. Website GeekWire first reported the move.
