Like the Earth, a sandwich is made of layers and gathers its strength from its meaty core, which pushes condiments toward the crust to erupt and bury fingers in deliciousness. Let rivers of mayo magma run with today's Groupon: for $5, you get $10 worth of sandwiches at Dave's Cosmic Subs. This Groupon is redeemable at Dave's Bowling Green and Perrysburg locations.

Dave's ambitious assortment of hot and cold subs handily thwarts even the most severe hunger pangs. Sub-smashers can demolish classics such as the signature Original Dave's Cosmic sub, stuffed with pepperoni, genoa salami, prosciutto, veggies, provolone cheese, and smothered with Dave's Cosmic Sauce (8", $5.49), or its larger, spicier brother known as The Big Dave, loaded with more meat, more veggies, and hot peppers (8", $8.99). Dave's original garden burger, topped with swiss and cheddar cheese ($6.49), provides a meatless alternative to satisfy vegetarian appetites. Smaller human fuel tanks can fill up on items including the kosher beef Davey dog, sprinkled with cheddar cheese and topped with Dave's #9 hot sauce ($3.99). The 8-inch subs are also available in larger, 16-inch forms fit to feed two hungry people or an overgrown ant farm.

Dave's Cosmic Subs' décor encapsulates all the magnificent splendor of the 1960s, with vintage concert posters and psychedelic artwork peppering the walls. Flower children's children bop their heads to the peace-loving beats of classic rock music from the Rolling Stones and Jimi Hendrix, and the hypnotic allure of Dave's tie-dyed merchandise reminds snackers of summers spent touring with the Grateful Dead and winters spent watching Lucky Charms dissolve in bowls of milk.

• As at the other Dave's locations, the decor inside this cosmic sub shop is a shrine to the ’60s full of rock references, hippie music and good vibrations. The overstuffed subs rock, too, built from top-notch ingredients piled inside a crisp-crusted Italian roll, for what is the very epitome of a first-rate sandwich. – Cleveland Scene
