Do you like pizza? What about infinite pizza? I thought so. In Porto Alegre, Brazil you can enter the all-you-can-eat "Nono Ludovico", sit down and just wait. In a matter of seconds, a waiter which has been already circling the restaurant will approach your table with a unique pizza. Now it's your turn to either say yes or no. If you say yes, a magical slice will find its way to your plate, whereas if you say no, the waiter will keep on circiling the restaurant, apporaching other tables with visitors that might not share the same taste as you and say yes. Not too long after that, another waiter will approace you with a different type of pizza, asking you to go through the same ritual, and soon enough you will find yourself munching through your 7th slice. WAIT. You thought that was over? Think again. It's time for some sweet pizzas. Once you've ordered the barrage of waiters to start handing out the sweet pizzas - you are done for. The gates of hell are now open, and you will be receiving pizzas that only pictures can describe, so here, have a look-see: Chocolate milk & white chocolate milk crumbs Strawberries and chocolate milk Dulce de leche Chocolate milk & almonds There are many restaurants that work on the same principal in Brazil, meaning that you don't have to go to this one specifically - but you can bet your bottom dollar that this is an exceptional place. The whole concept of just saying "Yes" or "No" to food is such an amazing user-experience - so start saving money for your flight tickets.
