# At Louis’ Lunch, the Same Broilers Have Run Since 1898
The hamburgers at Louis’ Lunch come out vertically. The patties hang in cast-iron gridirons inside vertical gas broilers, cooking on both sides at once without a flat-top griddle anywhere in sight, a setup the restaurant has used since the broilers were installed in 1898. They are believed to be the same broilers still in use today, more than a century later, at the restaurant’s current address on Crown Street in downtown New Haven.
Louis Lassen, a Danish immigrant who came to New Haven in 1881, started out as a food peddler selling butter and eggs from a wooden cart before adding lunch items in 1895. According to the Lassen family’s own account, the restaurant’s signature sandwich came about in 1900, when a customer in a hurry asked for something he could eat on the move; Lassen put ground steak trimmings between two slices of toast, and the hamburger sandwich, in this telling, was born. The claim has made Louis’ Lunch a fixture of hamburger lore — the Library of Congress recognized it as a New Haven “Local Legacy” tied to the dish’s origin — though the history of the hamburger is genuinely contested, with several other vendors around the country making similar claims from roughly the same era, and no definitive written record settling the matter either way.
What isn’t in dispute is the restaurant’s age and its staying power. Lassen moved his business into a permanent brick building, once a tannery, on George Street in 1917. In the early 1970s, the city’s urban renewal plans threatened to demolish that building, and New Haven residents protested to save it. The building survived the fight but still had to move: in 1975, it was loaded onto a truck and relocated several blocks to its current spot on Crown Street, with supporters mailing in bricks from around the world to help rebuild its walls.
The restaurant today is run by Louis’ great-grandson, the fourth generation of the Lassen family at the helm, and the menu has changed only modestly across more than a century. Burgers are hand-rolled from a blend of ground beef, cooked in the original broilers, and served on white toast — the Lassens still don’t offer condiments beyond cheese spread, tomato, and onion, a point of stubbornness that regulars tend to respect rather than resent. There’s no ketchup bottle on the table to ask for. The toast itself comes from a 1929 Savory radiant gas toaster, another piece of equipment that has simply never needed replacing.
Louis’ Lunch is small, with limited seating, and closes for the entire month of August every year, a vacation tradition as old as some of the restaurant’s hardware. It has drawn attention from national television and food press over the decades, but the appeal for New Haven residents has less to do with any title and more to do with continuity: a family still running the same broilers their great-grandfather lit, in a building that survived being moved across town to keep going.
