I tell you, when it comes to ingesting fish and other stuff that started life in the sea, then the west coast of Mexico is hard to beat. In San Blas, if you stop, close your eyes, spin around and open them again, then you are facing a fish restaurant.
These restaurants are rarely more than shacks with palm roofs and earth floors. The cooking is done over a very slow burning grill, more smoking than grilling really. The menu is look at the grill and choose what you want.
The market is overwhelmed with fish stalls.
I go to an upmarket restaurant, one that has a menu.
You look out onto the ocean. Frigate birds and pelicans drift by. The meal, with 2 mugs of homemade limonade, comes to $8:00.
