You make enough decisions in a day to drive you crazy. So, here’s an easy one: decide to hit Strega Waterfront for its new "Executive Lunch” prix fixe menu, then choose an app, entree and dessert. Among the app choices are roasted beet salad with whipped ricotta and toasted hazelnuts or Rosetta’s famous meatball; entrees include veal ‘Saltimbocca’ or crab and avocado salad; and to finish, either the chef Sal’s famous tiramisu or ricotta and chocolate chip cannoli. Easy, right? Did we mention it’s a steal, too? At $20, it is (11:30 AM-3 PM; excluding tax and gratuity; 617-345-3992).
