Steak is useful for exercising incisors, muffling trumpets, and reducing swelling from black eyes caused by trying to eat steak with one's eye. Put steak to its prototypical use with today's Groupon: for $10, you get $20 worth of American fare at Oracle Inn Steakhouse in Oracle. Oracle Inn sears, encrusts, smokes, and charbroils a selection of steaks and sandwiches in its southwestern restaurant and lounge. The hearty menu bursts with meaty offerings such as the buffalo burger ($9.99) and steak au poivre ($16.99); authentic German fare such as the wienerschnitzel ($21.99) fills plates the second weekend of every month. For children, whose small mouths cannot accommodate a slab of sirloin, Oracle Inn serves six kids' menu items such as the mini plate of two tender barbecue riblets ($4.99).
