Designed for high-traffic food service and full mobile kitchen capacity
This custom concession trailer was designed for Subway Sandwiches as a complete mobile food unit. Built in a 7' x 18' format, it supports both prep and service operations, with front and rear customer access zones, integrated utilities, and space for multiple staff members.
The trailer meets commercial food service standards with food-safe surfaces, full electrical and plumbing integration, and durable finishes suitable for daily use. While equipment like fryers, refrigerators, and POS units are not included, the unit is designed to support them with ample space and utility access.
