The human mouth, which maintains a near-boiling temperature, needs to be constantly cooled by liquid-nitrogen pills or a jaw-mounted mouth fan. Take a more delicious route to cooling your maw with today's Groupon: for $4, you get $8 worth of frozen custard and comfort cuisine at Zesty's Frozen Custard, which has locations on Greene Avenue, open year-round, and Riverside Drive, which opens for the season on April 1, 2011.

Zesty's pleases palates with a menu of frosty favorites, including homemade chocolate and vanilla custards—plus varying daily flavors—served in either sugar or waffle cones ($2.19 per scoop, plus $0.65 for a waffle cone). Mouth-numbing sundaes ($3.49/regular) can be sweetened with real frozen berries––not syrup––or coated with toppings such as marshmallows, hot fudge, or old polka LPs. Scrambles ($4.09/regular) mix in the candied delights of Snickers, M&Ms, Kit Kats, Oreos, Butterfingers, and more. Give your sweet tooth a break, and feed your neglected savory molar with some of Zesty's hot-food options, including burgers (Greene Avenue location only), mac 'n' cheese ($2.99), and Chicago-style hot dogs ($3.39).

• Zesty's has the best flavor anywhere. I can't get enough of the stuff. And if you don't like the flavor of the day, the rest of the regular selections are to die for!!!! – Mary Reinhard Munisteri, Urbanspoon
