In a city used to sameness when the issue is food, any chicken foot is a pretext for a party. This is the case of Madero. Self-acclaimed as "the best burger in the world", the chain - whose restaurants are popping up at a pace that would make McDonald's blush - introduced the “gourmet burger” trend to Curitibans. Be cautious, though, not to be influenced by the appearance of the locals that dress up for the weekend evenings just to go out to eat at a nearby Madero. Yet somewhat pretentious and trendy, the restaurants are informal places. Therefore, do not hesitate to dress shorts and tee, if you so wish, do go out for lunch or dinner.
The several restaurants look somewhat alike, resembling the first property opened in the historic center of the city. Ambiance does not prioritize comfort and privacy, as there usually are more tables than what would be recommendable. Likewise, some restaurants lack a pro-made acoustic project, as they always sound over-noisy. The one in downtown Curitiba is the worst for both topics.
The burgers are just OK and are offered in just two versions (cheeseburger and cheesebacon), three sizes (one, two or three paties) and made out of three meats (beef, lamb and pork). The burgers’ presentation is absolutely conservative and lacks, in every sense, creativity and innovation, as the bread, dressing (mayo, lettuce and tomato slices) and side - just pale, mushy French fries - are the same for all them. Yet disappointing and frustrating, burgers are pricey (from US$ 11 up), though. Given all this, the moto "the best burger in the world", sounds not just over-pretentious, but untrue, as well. Therefore, self-acclaiming itself as "a good burger in town” would sound more appropriate and realistic.
Service is just OK, as well, yet always uncertain, given correctness and promptness change from place to place, in spite the fact the staff looks over-dimensioned in every property. Likely erratic is the burger cooking point - something customers are NEVER asked about when ordering - which may come pinky or well-done inside, depending only upon the cook's mood. Unforgivable for such a pretentious place like this is the fact that all the isolating sleeves the large beers are served in, are dirty, slimy and moldy inside. In spite my personal warnings in two different occasions, it seems the issue has been neglected given the problem persists. From the other plates on the menu, do not expect much, given they are just average, but pricey!
