Absurdly big (and good) burgers
New York Burger is standard fare in the gourmet burger Renaissance currently underway in Madrid. While a lot of places get kind of cheesy (i.e. shrimp burgers, etc.), this place does big burgers simple, well-cooked, and delicious.
You have the choice of 150g., 250g., and 500g patties (1/4, 1/2, and 1lbs., respectively), and I'd suggest the monster 500 grammer if you're hungry. The thing was so big it made me laugh when it came out. It dwarfed the bun. I ordered the Bronx in specific, I believe, which came with cheddar cheese, smoked bacon, and guacamole. For reference, the patty was 1.5in. thick and about 6in. across...it was huge! They cooked the meat exactly how I wanted it, and the fries were pretty good too.
