Life would be pleasant indeed if you had a pizza oven in your own back yard — complete with a skilled pie baker, of course, because nobody wants to get hot and sweaty when patio drinks beckon. The next best thing is Kaos Pizzeria, where you can relax among friends, surrounded by flowers, trees and the delicate aroma of potted basil. Kaos is built into a vintage Victorian on Old South Pearl Street, with a tiny dining room inside, but the best seats are on the expansive patio, which wraps around the side and back yard of what was once someone's cozy home. The sunlight is always dappled and the beers are always cold in this neighborhood spot. And the pizza comes with crisp, charred edges wafting with the aroma of wood coals — just right for a summer night.
