Subway is an American privately held fast food restaurant franchise that primarily sells submarine sandwiches (subs) and salads. Subway is one of the fastest-growing franchises in the world and, as of June 2017, has approximately 45,000 stores located in more than 100 countries. More than half of the stores are located in the United States. It is the largest single-brand restaurant chain, and the largest restaurant operator, in the world.
Subway’s international headquarters are in Milford, Connecticut, with five regional centers supporting the company’s international operations. The regional offices for European franchises are located in Amsterdam (Netherlands). The Australian and New Zealand locations are supported from Brisbane (Australia). The Asian locations are supported from offices in Beirut (Lebanon) and Singapore and the Latin American support center is in Miami.
Subway’s core product is the submarine sandwich (or “sub”). In addition to these, the chain also sells wraps, salad, paninis, and baked goods (including cookies, doughnuts, and muffins). Subway’s best-selling sandwich, the B.M.T., contains pepperoni, salami, and ham. Subway also sells breakfast sandwiches, English muffins, and flatbread. In November 2009, Subway signed a deal to serve exclusively Seattle’s Best Coffee as part of its breakfast menu in the US.
All the ingredients with in the restaurant are always fresh and new. This is important because when a customer walks in to order food, they can see the employees make it for them. Customers would not like it if the level of hygiene/freshness of the food was bad.
On the other hand, it is acceptable to have second hand equipment if it is still in fully working order. This is does not affect the quality of the food or the service a customer is having. This can potentially save subway some money where they can use it to invest it in something else.
