Big Daddy Burger Bar
For a deeply local experience, trek out to Big Daddy Burger in the south of Budapest, located a half-hour away from downtown by bus. Flanked by drab communist-era high-rises lies this quirky place inside a flimsy wooden shack, painted in red, white and blue. The kitschy 'Merican decor — I'm not sure whether it's ironic — features plenty of tchotchkes and decorative license plates from states like Texas, Florida, and Missouri.
Big Daddy's burgers are very tasty, in party because they come in smaller and squishier buns than elsewhere in Budapest, making for an ideal patty-to-bun ratio. The default doneness level is just over medium, but you can specify how you want yours cooked. Of the 28 available burgers options, I usually go for the “Még egy kis hús - bacon burger” packing cheddar and strips of crispy bacon (€4). Another reason to journey out to Big Daddy is the prices, which are about half of what you'll need to cough up in downtown (the classic cheeseburger runs just €3).
