Some students took me to a pizza place in Plaza Mayor. Usually eating in a plaza would be a bad idea given that's how tourist traps work. However at least this place was a mixture of enticing and some imaginative interior design. It's a pizzeria and a cerveceria meaning night may be even more atmospheric.
Pizzas are shown in the window but different ones are available inside. They are about 22-27€/kg which works out to be about 3-4€ for a 140gram slice that they approximate, which makes 10€ per lunch or so. Of course you can ask for mas o menos or try more range.
The best part is that before serving, they put it in an oven/grill which crispens the oily base and also melts and chars the toppings, particularly the cheese. It's an excellent method and one I will now adopt to home cooking.
I tried 6 types of pizza in 2 sittings and all were good. My favourite would have to be one with zucchini and provolone with anchovy running through it - excellent flavour. Others include in that same photo pumpkin/panceta and cherry tomato/basil, and in the second photo mushoom/pesto/tomato, 4 cheese and anchovies/mozzarella/red peppers.
Of the pizzas I've sampled from Australia, London, Italy, NYC and Argentina, I'd probably say it resembles deepdish NYC or Argentina the closest. Very impressed.
