Two words: Cuban sandwich!
The best (we have never been to Cuba, so we don't know where to find better ones).
The corn on the cob is a very good starter, if you go for dinner. Of course, accompanied with a fresh cerveza or a frozen mojito. There is almost always a waiting line, but it is the game and everyone chill on the sidewalk.
We also tested their Malibu outpost and it is perfectly located to continue your road trip on Highway 1.
