As I understand it, the "X" that comes before every burger on a Brazilian fast-food-style menu indicates that the burger will have, at the very least, cheese. That's because the letter X is pronounced "sheesh" in Portuguese, a sound which comes very close to sounding like "cheese." So a X-Tudo burger on the Friends Pizzeria menu means that you're getting a cheeseburger "Tudo" -- with almost everything.
Everything means everything: bacon, ham, peas, corn, potato sticks, tomatoes, lettuce, mayonnaise and even a fried egg. It's a burger that's difficult to eat, for sure, but rewarding. I liked the pleasant crunch provided by the peas, corn and potato sticks, although I wasn't a fan of the extra-fatty bacon used on the X-Tudo ($6.95). It reminded me of the fatty bacon used in an English fry-up or a bacon buttie. Give me some American-style crispy bacon any day of the week.
What I loved, however was the pizza.
