The One Roast Beef & Pizzeria has been operating in West Yarmouth since 2014, built around a straightforward premise: fresh roast beef sliced daily to order, medium-rare and thin-cut, served on rolls alongside steak subs and house-made pizza. The kitchen makes dough fresh each morning—sometimes twice daily—for pizzas and pita bread, and prepares most menu items in-house. Beyond the signature roast beef, the menu extends to char-grilled steak tips, chicken kabob, rice plates with oven-roasted beef, salads, and wraps. The owners emphasize that despite the fast-service format, they source quality cuts of meat and avoid shortcuts in preparation. The place handles catering and draws repeat customers specifically for the roast beef sandwiches.
