Maoz: It is a vegetarian fast-food. You will be served with falafel just cooked (ffried) in a pita bread, then you should make your sandwich choosing between ingredients prepared and placed on the counter, and without any check you can fill your sandwich as much as you desire.
The quality is good, all vegetarian, hummus, yogurt sauce, vegetables prepared in various ways, and fried vegetables, spicy sauces ... Even the fries are excellent, cut a bit 'rough and served in a paper cone. The price for a falafel pita is 4.50 €. There are 2 Maoz virtually identical to each other, one on the side of the entrance to the Boqueria market, one in Carrer de Ferran, next to Plaza Reial.
Open from morning until after 24:00.
