If you've seen the trinkets and dangling Corona bottles that adorn the walls of Mexi & Co, you'll know what to expect from its sister venue El Sol y La Luna. Here too, the food is cheap 'n' cheerful, the vibe is sociable, and the décor is set firmly on 'quirky'.
The weekday lunch menu offers the best deal: main course, dessert and a coffee for €10 (up to €19 on weekends, with a starter thrown in). The locals know it, and you should aim to arrive early if you want to find a seat. The menu throws up a lot of Latin American dishes but few surprises: tortillas, quesadillas, soups, salads, burritos and (delicious) empañadas are the order of the day here. If you're after subtlety you're best off trying somewhere else, but if you're hungry and looking for a stopgap you could hardly do better.
A word of warning: prices jump at dinnertime to €28 for a set menu including a starter and a cocktail.
