What I like about Subway is the ability to actually see the food in front of one as it is placed on the sandwiches. This is a customer-driven quality control feature. One can see the product, see how it is made, see the level of cleanliness/hygiene, see if gloves are put on and/or changed.... So, from fresh materials in front of one to a sandwich that is either cold or heated -- one can see the entire process. Frankly, the Subs are healthy compared to the oil ladden products of other "fast food" places. My experience with staff has been they've been friendly and helpful in all instances.
f8 and be there.
