SP Burger looks like an American-style fast food chain, but the only one I found was at the international airport. It has the usual choice of hamburgers, chicken sandwiches, hot dogs, and shakes.
I got the Combo Cheddar Bacon (without cheddar) for a measly R$21.90 ($13.15)-beat that Geneva! The burger comes on a brown bun and has a thick but very salty patty (not pure beef) and a sad piece of bacon. There is no sauce on it, but you can get ketchup, mayo or mustard. The McDonalds-type fries were undercooked.
VERDICT: 44/100
I would say that SP Burger is better than Bob's Burger, but that is as far as I would go. Next time I want fast food in Brazil, I will probably go to McDonalds. Nuff Said!
