Eating is necessary for human survival, along with breathing, sleeping, and remaining still while a curious velociraptor rummages through your closet. Practice survival tactics with today’s Groupon: for $5, you get $10 worth of German and Polish fare at Edelweiss Café & Restaurant in Clarksville.

Authentic German dishes and homemade pastries crowd Edelweiss' menu, which is served in a homey restaurant festooned with Bavarian décor and recommended by TripAdvisor. Half of a rotisserie chicken ($9.99) dances along a crispy french-fry border, and traditional Bratwurst sausages ($9.49) rest on a bed of sauerkraut, which cooks shredded after it revealed incriminating information. Inside the schnitzel sandwich ($7.99), a breaded pork cutlet smothered in special sauce lounges atop brotchen, and the handheld morsel accompanies a side of homemade german potato salad. German soda and beer wash down post-schnitzel shoveling, and a rotating selection of freshly baked cakes, cookies, and tarts conclude meals as sweetly as fairy tales penned in maple syrup.
