An old bank building in University City was converted several years ago to a combination root beer brewery and family restaurant, Fitz's draws an enthusiastic crowd of college students, adults and children. Diners can watch the root beer making and bottling processes through a large glass partition, all the while enjoying good pub food such as hamburgers, pizzas, etc. The root beer, a revered St. Louis formula that dates back to an old roadside stand from the 1940s, is terrific, too.
