New Haven Celebrates Louis' Lunch on National Hamburger Day

As May 28 "marks National Hamburger Day in the U.S., once again drawing attention to an American icon, Louis' Lunch," the city will celebrate the eatery, according to a release from Visit New Haven.    "In 1900 Louis Lassen created the first hamburger sandwich for a customer who needed an item to go, long before the drive-thru window. Hand grinding some beef and placing it between two slices of toast, a legend was born," the release said..   "Documented by the Library of Congress as the birthplace of the hamburger sandwich, the original process remains unchanged. The burgers are made fresh daily by hand-rolling a proprietary blend of five meat varieties. The burgers continue to be grilled in the original vertical cast-iron grills dating back to 1898."   "The first question out of many visitors' mouths is 'Where is Louis Lunch'?'" said Visit New Haven Executive Director Ginny Kozlowski, also in the release . "With national and international media coverage and world-wide acclaim, Louis' is truly a national treasure.".   Also noted in the release:  Louis' Lunch is open, Monday and Tuesday 11 a.m.-3: 45 p.m., and Thursday-Saturday noon-2 a.m. Bring cash, as credit and debit cards are not accepted. Visit New Haven is a department within REX Development, the release said.
