If you are into food, I think you will like Guadalajara. As a big city it offers a huge variety, from best Mexican cuisine to all kinds of international dishes! And no matter if it´s a simple taco stand or an upper-class restaurant, in Guadalajara you´ll get an unbeaten value for money.
I would even say the city would be worth a visit JUST for the food! During my time there I aimed to try every recommendation I got and, as an outcome, here are - only and exclusively - my absolute favorites.
