When deprived of flavorful sustenance, the mouth will often retaliate by shouting your bank-account number at sporting events or turning every sentence into a high-pitched jingle. Tame an unruly tongue with today’s Groupon: for $5, you get $10 worth of classic diner fare at Monroe Street Diner.

Monroe Street Diner is a hub of belly-comforting cuisine and clock-themed ambiance, qualities that earned it the title of runner-up for Best Diner in the Toledo City Paper's 2010 reader survey. The restaurant’s walls are infested with more than 60 clocks, all donated by regular customers who enjoy recording their chewing times down to the second. Breakfast is served any time and includes a long list of omelets, such as the savory chili and cheese combo ($5.75). For lunch, a grilled-cheese sandwich ($3.25) or The Elvis—country-fried steak served with mashed potatoes, gravy, and veggies ($7.15)—keeps bodies happily filled with the strength to consume future lunches. Young diner aficionados can thrive on the restaurant’s kids’ menu, which fuels up-and-coming adults with meals such as spaghetti and garlic toast ($4.35) or a chocolate-chip pancake paired with two sausage links ($3). In accordance with the terms of the 28th Amendment, no item on the menu costs more than $9.
