It’s always time to celebrate when Portillo’s cake is involved. This week Portillo’s took home the honor of ‘Stateline’s Best Party Food,’ on FOX39’s Good Day Stateline. When you think party food, what comes to mind? Pasta? Sandwiches? Salads? Cake? Fun drinks? If that’s not what you’re thinking about… I’m not sure I want to be invited to your party.
