There’s lots of museums in Mexico City, but one of the easiest and most pleasant for a quick visit is the Estanquillo. It’s half way between the Zocalo and Bellas Artes on Madero, and easily noticed thanks to the funky picture windows. And as easily missed thanks to the small, slightly non descript entrance at the side on Isabela la Catolica.
The museum is full of cartoons, caricatures and other historical art work along with a few fun exhibits. It’s free to enter every day of the week, they allow photography (although it’s very dark inside and flash is not allowed) and have the funkiest little terrace with a cool view of church rooftops and the busy streets below. It’s the sort of place that’s ideal for a flying visit if you have limited time, or a lengthier stay if you fancy a chat on the terrace.
