Budget 20 euros
I'd suggest Vapiano. It's a great Italian place with delicious fresh pastas and pizzas and a great atmosphere. The prices are quite low if you consider the quality of the food (about €7 for a fresh made pasta or pizza). If it's busy opt for pizza, since you don't have to wait in line for that (they'll hand you a buzzer). They have two restaurants. One near the Markthal (market square) and one near Central Plaza (in the Plaza shopping mall).
