@tsarstepan,
The best sandwich in Los Angeles, last I checked (2009), is still the meatball sandwich at the international food place on Lincoln in Santa Monica, near Broadway. When I knew it as a neighborhood place, it was called Bay Cities, and international grocery store with deli. The meatball sandwich was best eaten on one of the ugly benches and tables facing Lincoln Boulevard in the rain, the wind, the smog, the car fumes.
