Firehouse Subs is ramping up its delivery platform. The 1,145-unit sandwich chain announced September 13 that it has partnered with Uber Eats to bring the service to hundreds of restaurants nationwide. Already, nearly 500 Firehouse locations are live on the platform. The company said it plans to feature 700 by year’s end. Uber Eats is also fueling McDonald’s massive delivery growth.

“Through third-party delivery, we’re able to widen our franchisees’ business while also offering our brand to customers where and when they choose to enjoy our food,” Firehouse Subs chief financial officer Vince Burchianti said in a statement. “Uber Eats is the premier delivery service provider, with the ability to increase brand visibility among off-premise consumers that otherwise might not consider Firehouse Subs, ultimately driving incremental revenue to our franchise family.”

Firehouse said the partnership would allow it to better service its franchisees by expanding their sales channels.

“It’s our mission to make food delivery an everyday thing. Whether you can’t step out of the office and need a quick lunch, or are simply craving your favorite, subs have become increasingly popular on Uber Eats,” added Liz Meyerdirk, global head of business development at Uber Eats. “We’re excited to work with a best in class brand like Firehouse Subs, to deliver delicious subs to more people—that includes both faithful customers and those who are simply looking for something new to try.”
