To subvert grumpy monarchs, angry medieval youths scrawled condiment graffiti such as "Fran Tanner has plague" or "the king is a jerk" inside their sandwiches. Dig beneath lettuce to bring history to light with today's Groupon: for $6, you get $12 worth of sandwiches, salads, soups, and more at Silver Mine Subs. Choose from the following locations: Boulder, Denver, Greeley East, Greeley West, Loveland, and the Campus West, Council Tree, Magnolia, and Harmony Road locations in Fort Collins.

The sandwich artists at Silver Mine Subs take a no grilling or frying approach to designing bread-bound eats, putting the spotlight on fresh, crisp ingredients. Browse the menu in search of the Steam Engine, a warm hoagie stuffed with meatballs, marinara sauce, and provolone (5", $4.19), or the turkey-and-avocado-packed Caribou (8", $5.79). For a more flavorful punch than a chocolate-dipped boxing glove, patrons can aggravate the Mother Lode's layers of roast beef, turkey, ham, and salami (11", $9.79). Complement subs with a piping-hot cup of broccoli-cheese soup ($2.99) or a garden salad sprinkled with fat-free ranch dressing ($3.99).

Accommodating hungry moonbeams, Silver Mine Subs serves its subs until 3 a.m. every day of the week. The ever-wakeful staff is ever friendly and ever striving to make service convenient to customers, lobbing into their hands the most delicious submarine sandwiches since prospectors struck white gold during the mayonnaise rush of 1854.
