Street Market

[Izzenhood]

While in Guanajuato ten years ago I was walking along Tepetapa towards the Mummy Museum. Somewhere around the train station there was a scruffy street-market with little or nothing open, or for sale. I've always wondered whether that mercado was only busy on a certain day.
Is that mercado still there, and when might it be busy?

I am familiar with Mercado Embajadoras. For those less familiar with Guanajuato, Mercado Embajadoras is south of El Centro on the road to Presa De La Olla. Embajadoras is the local daily market and is worth a visit.
