I'm also amazed at how many of these restaurants I've been to.
I'm sad to know that La Fonda has closed. We tried to go to Langers one night with MP & H but they close early. It's in a really nice area.
I spent many a night at El Coyote drinking cheap margaritas and eating chips and salsa. My other favorite place of my youth was the Frolic Room. It was pretty old school before the Pantages was brought back from near death.
However, I've never been to the Americana, which I drive by on a regular basis.
