Bæjarins Beztu Pylsur is a legendary hot dog stand in Reykjavík, Iceland, known for serving up delicious lamb hot dogs with unique toppings like sweet ketchup and remoulade. Established in 1937, this family-run joint gained international fame when former US President Bill Clinton ordered a hot dog there during a visit. Since then, it has become a must-visit spot for both locals and tourists looking to try the iconic Icelandic hot dog experience.
