Lay down your wallet and pick up a microphone. Sing for your supper! On Monday, April 18, the Hard Rock Cafe Denver in the Denver Pavilions (on the 16th Street Mall) opens up its stage to give customers a chance to “sing for your supper.” Guests brave enough to take the stage and sing in front of the entire restaurant receive a FREE Local Legendary Burger. Served on a toasted brioche bun, the burger features a Certified Angus Beef patty topped with smoked bacon, cheddar cheese, a golden fried onion ring, crisp lettuce and vine ripened tomato — with seasoned fries. To qualify, you must be at least 18 years old and perform a full song from a list of designated songs. (If you’re under 18 years old, you must be accompanied by a parent or legal guardian.) The microphone is turned on from 6 p.m. to 8 p.m. The offer is first-come, first-served, so be sure to get your name on the sign-up sheet as soon as possible. With such a delicious freebie, you just might forget about any stage fright or nervous jitters — just have fun!
