Subway opened a global headquarters in Miami to supplement its existing headquarters infrastructure in Connecticut, the company announced Thursday. The Miami headquarters will play host to about 150 corporate employees, including Subway’s Latin America regional office staff, along with some consumer-facing functions. The HQ includes an “Innovation Center and Mock Restaurant,” according to the press release.

The mock restaurant will enable Subway to experiment with menu and operational tweaks, “allowing employees to constantly collaborate and experiment with the culinary team on new sandwich builds and products,” the company said. “Modeled to resemble a real Subway restaurant, the Mock Restaurant provides a dedicated space to test products in a real-life setting.”

The location may improve cooperation between the company and its franchisees, CEO John Chidsey said. 

“The strategic placement of our new office opens the door for an even stronger integration with the Miami-based Independent Purchasing Cooperative, Subway’s franchisee-owned purchasing and supply chain cooperative,” Chidsey said in the press release.

Subway’s emphasis on menu innovation and collaboration with franchisees aligns with the chain’s ongoing efforts to shake up its menu and overhaul its franchise system as the chain approaches a potential sale.
