Ask any Santiaguino the best sandwich they've ever had and they will wax on about el lomito. Marinated pork slow-roasted, shaved, and piled high onto a sandwich with copious amounts of mashed avocado, homemade mayo, and tomato slices--beer on the side. The institution and reference for all things "lomito" in Chile were born at Fuente Alemana. Grab a seat at the counter and let the 30-year veteran waitresses make you an "italiano" with the fixings. Don't even think about trying to pick it up--fork and knife a must.
