Ok, before someone starts thinking bad about me
, let me explain why I know that place.
La Olla Caliente is located at Corredera Baja de San Pablo, just opposite a Dia shop where we used to buy before they opened a nearer one to my house.
Also, this place is fairly well-known because there are only a few "erotic" restaurants in Madrid.
As for the Museo Erótico, I'm only up to the minute regarding tourist information in Madrid so I know when a new museum / place is opening and also I know about changes (eg. the Prado museum will be opened on Sunday evenings in July and August 2001).
