About Lou G. Siegel

Lou G. Siegel is America's foremost Glatt-Kosher culinary organization, serving private families, corporations, hospitals, universities, and airlines since 1917. This site is the official home of our three specialized divisions: Lou G. Siegel Catering for galas, weddings and executive affairs; Radish Wholesome Eats for healthcare and academic dining; and Zetko Aviation Logistics for in-flight and charter meal service.

Everything we prepare is produced in our state-of-the-art commissary at 58 Dobbin Street in Brooklyn, New York, under Orthodox Union and Tartikov Beth Din certification with a Mashgiach Temidi — a resident rabbi on premises one hundred percent of the time. Our kitchens also hold ETIMAD Halal certification, so a single production facility can serve mixed-observance guest lists without compromise on either standard.

This site exists for planners and procurement teams who need one dependable partner for kosher food at scale. Use it to explore each division, review our certifications and century-long heritage, browse the Jewish calendar for 2026–2027, and submit an inquiry describing your event, meal volume, dietary specifications and timeline. Every request reaches our team directly — there is no automated ordering layer between you and the people who will actually cook and deliver your food.

We build and maintain this experience ourselves, as the Lou G. Siegel family of brands, so that the information you read here reflects exactly what our kitchens can deliver today. For a direct conversation, call 212-921-4433 or visit our contact page.
