According to Emily Post, napkins may only be used to cover laps, clean up spills, or signal the waiter via semaphore that your table has hit an iceberg. Master restaurant etiquette over an appropriately refined meal with today's Groupon: for $30, you get $60 worth of contemporary American cuisine and drinks at Noca.

An ever-changing menu of comforting dinner staples and cutting-edge edibles prompted the Phoenix New Times to name Noca the Best Contemporary American Cuisine winner in 2009. Although the menu varies, recent customers have soothed performance-anxiety-ridden taste buds with a bowl of chilled Brentwood corn soup infused with chorizo croquettas, avocado, and extra virgin olive oil ($11), or sampled a mouth-puckering plate of pork belly with burrata, marinated heirloom tomatoes, and basil aioli ($14). Decadent entrees showcase sophisticated flavor pairings, such as squid-ink linguini with squid, clams, mussels, shaved fennel, garlic, chili, and mint in white wine broth ($24). A veal porterhouse rests upon a roasted summer squash, king trumpet mushrooms, english peas, and cannellini beans dressed with a spring-garlic demi ($33), and a meat-free plate of cipollini onions, baby carrots, seasonal squash, and polenta pavé provides a refuge for vegetarians as effectively as a wilderness stegosaurus refuge ($20).

Before slipping into a food-induced slumber, frolic through one of Noca's desserts, such as a trio of warm donuts with milk jam, blueberry jam, and Nutella ($8). Fanciful cocktails fill tumblers or customer-provided dunk tanks with specialty liquors and fruity bitters, and an expansive wine list brims with sweet nectar from California and Europe.
