Market (Mercado) of San Miguel in Madrid is a redone market with tremendous vendors, ham, cheese, fish, meat, wine, beer. Anything and everything to stock your larder or eat out.
The last time we went we scored a variety of foods. Of course ham, Iberico de bellota
We had some oysters, that were the brineiest I've ever tasted
You can almost imagine the salt on these
We had some paella rice (all of this shared between 3)
and some pork rinds (chicharron)
We love this market and hit it every time we are in Madrid. Fun place with great food.
