Ninety percent of alleged UFO sightings can be easily explained as falling meteors, swamp-gas reflections, or doughy orbs hurled into orbit by Herculean pizza makers. Enjoy earthbound eats with today's Groupon: for $20, you get $45 worth of pizza and more at Vivid Pizzeria in Regal Heights.

Vivid Pizzeria purveys authentic Italian pies prepared from a special house recipe with premium ingredients and daily-made dough. Rustic, thin-crust creations include the Parmigiana ($14), adorned with crushed san marzano tomatoes, italian sausage, roasted eggplant, and parmigiano cheese, as well as the spicy Coviello ($13), which throws salami and hot chili peppers into a ring to duke it out for each biting damsel's affection. The Vegetariana ($14) forsakes pizza's customary red colouring for a white base bearing roasted eggplant and zucchini fashioned into delicious top hats. Diners can forego dough with salads such as the Spiedini ($10), which presents four prosciutto-wrapped mozzarella skewers on a bed of arugula. A dessert of Grandmother Cake ($7), involving lemon-accented pastry covered with pine nuts, almonds, and powdered sugar, stands by to provide a sweet finale and a comforting bedtime-story voice.
