Granja València

They have good cold cuts for breakfast and pretty good prices for the area. They're fast.

Traditional place where you can eat well, they have a grilled chicken that I don't know how they make but it turns out perfect, they also have a weekday menu that is delicious

€11.50 full menu with drink, starter, main course, and dessert or coffee, fast service, everything very tasty, air conditioning

Chinese bar with a daily menu. It's nothing special, but it's the most affordable option you can find in the area.

I visited around 10 a.m. and ordered a simple set menu (coffee and toast). The staff was incredibly friendly and helpful (choice of Americano/latte, iced tea, etc.). I was able to fully enjoy Barcelona outdoors, just after the rain.
