Amazon is expanding its local restaurant meal delivery service to San Francisco today and now covers 117 restaurants across 33 zip codes, with more to come in the following weeks.

The Internet giant first introduced meal deliveries in Seattle back in September, before expanding to cover Los Angeles, Austin, Portland, Baltimore, San Diego and Chicago. Available to members of the $99 annual Amazon Prime subscription, the Prime Now app offers a myriad of perks, including one-hour and two-hour deliveries on various goods. But the company is also now looking to further encroach on the likes of Uber and Postmates with its expansion into meal deliveries.

Through the Prime Now app, a user plugs in their zip code to see if the service is available. Where meal delivery is open for business, they’ll see a “Restaurants” option on the homescreen. Participating outlets at launch include 5 Sweets, Mezes Greek Kitchen & Wine Bar, Big Chef Tom’s Belly Burgers, Buca di Beppo, DOSA, The Monk’s Kettle, Nick’s Crispy Tacos, and Pressed Juicery. Amazon promises to have the food at your door within the hour.

In an interesting addition, Amazon has also announced a “no menu markup guarantee,” meaning that if you find a food item listed through Prime Now that is priced higher than on the restaurant’s up-to-date online menu, Amazon will refund the full price of the item within 24 hours, though it looks like Amazon is only committing to this guarantee until the end of the year.
