Though spontaneous singing used to be considered improper outside of the shower stall, it has gained acceptance thanks to the increasingly common practice of splicing songbird genes onto human DNA. Treat your ears to a tune with today's Groupon: for $5, you get $10 worth of gelato and café fare served by the talented musicians and songstresses at Sweet Melody's in Clarence.

The staff at Sweet Melody's is largely made up of college students studying music or voice who are apt to leap from behind the counter and serenade patrons at any moment. Sweet Melody's also dishes out tasty harmony with its menu. Fresh mozzarella and fire-roasted peppers sing without amplification in the A Cappella panini ($7.25). Meanwhile, the Stacatto panini attacks each flavor note with fervor, powered by dijon mustard and then supplemented by ham, asiago cheese, Placido Domingo, and basil leaves ($7.25). Visitors can also blend the small-size gelato—the piccolo ($3.50)—with their choice of dozens of Sweet Melody's rotating flavors. Bigger sizes range from $4.30 to $5.30.

The staff's musical repertoire is as broad as Sweet Melody's 60 to 70 gelato recipes, encompassing Broadway, opera, classics, and country, as well as piano, violin, and guitar instrumentals. Thursdays are designated open-mic nights, but customers can feel free to sing along with the staff or turn the dining room into a choreographed stage adaptation of teen diary entries. Check the sorbetto and gelato RSVP list to earn an enthusiastic ovation from your taste buds.
