For many years, John’s Sandwich Shop (8913 W. North Ave.) has been an inconspicuous fixture tucked into a busy Wauwatosa business district, a neighborhood destination for good and modestly priced breakfasts and lunches. Recently, John’s freshened its interior and reinvented the menu for healthier eating. Did you know that yogurt helps prevent hypertension or olives are an anti-inflammatory? Such are the captions on the new menu, an offering with a slight Mediterranean accent. Among the delights are a Caprese burger, a Greek-style omelet and pomegranate pancakes—a delicious (and generously portioned) variation on an old American favorite.
