Like an urge for a thrill, a craving for Mexican cuisine can usually be satisfied by ingesting extremely spicy chilies or by diving off a skyscraper into a trough of guacamole. Free-fall into full-bodied flavors with today's Groupon: for $10, you get $20 worth of Mexican fare at Vista Grande Mexican Restaurant, valid at the St. Peters location.

Vista Grande rouses visitors' appetites and spirits with flavor-filled Mexican fare served in an eclectic, cantina-inspired atmosphere. The menu's entrees duke it out for diners' approval like capoeira-trained ex-spouses, showcasing traditional dishes such as chili rellenos stuffed with monterey jack ($8.95) as well as north-of-the-border plates of spiced-pork medallions ($10.50). The mountainous Ozark burrito fills its flour tortilla with seasoned beef and guacamole before being smothered in chili con queso and red sauce ($9.75). Margaritas come in flavors ranging from traditional to peach, and their span of sizes maxes out at the 46-ounce Grande margarita, which provides enough vitamin C to make an orange grove blush. A full children's menu is also available to give little tykes something to push around on their plates as they wait for dessert.

The dining area's colorful configuration features walls adorned with Mexican tapestries and sculptures, as well as ceilings bedecked with festive lamps. Vista Grande provides patrons with an entertaining respite from drab dining rooms and stuffy prison cafeterias, allowing guests to cozy up to the bar to catch a game on one of 10 big-screen televisions while they graze on grub.
