âIâm from out of town, and I like a good pastrami sandwich,â said Jeffrey A. Devore, a lawyer from West Palm Beach, Fla., who was sitting in Katzâs, the Lower East Side delicatessen that, like the neighborhood itself, has become a study in contrasts.
Mr. Devore had driven into Manhattan in his rental car after a court hearing in Newark and had taken a seat amid what a critic once described as the âterrazzo-and-Formica ambience, with a cafeteria counter along one side and signs instructing you, as of yore, to âSend a salami to your boy in the Army.ââ
Beneath the long, bright fluorescents that illuminate that comfortably old-fashioned backdrop, Mr. Devore opened his iPad and began reading The Wall Street Journal.
It was enough to make one wonder how to say âplus ça changeâ in Yiddish.
But even Katzâs, at 205 East Houston Street, at Ludlow Street, has adapted as the landscape has been remade.
In the very next block is an apartment building with a Web site that says two-bedroom apartments start at $5,500 a month; a gelato store and a nail salon occupy the first-floor storefronts. Katzâs is now open 24 hours a day on weekends, in part to accommodate younger, hipper customers who are out later than late. In the old days, no one risked being on the street on the far side of midnight.
âIt was a very tough neighborhood,â said Alan Dell, 65, one of the owners of Katzâs since 1988. âDrugs and that kind of thing. You felt nervous about coming.â
His son, Jake, 25, added: âYou ran in from the car and ran out. This was a safe place, always, but not the neighborhood.â
Now, Alan Dell said, the neighborhood has multimillion-dollar condominiums.
âWhoâd have thought?â Jake Dell said.
The pickle barrels no longer line Ludlow Street (they now occupy a storage room inside Katzâs). The corned beef and the pastrami are still cured the same way they always were, using airtight barrels and a salt solution with a formula that remains a secret (as do the formulas for the wood chips in the smokehouse where the pastrami is cured and the rub that is applied to it).
But Katzâs has served Reubens for a decade â" corned beef, sauerkraut, homemade Russian dressing and melted Swiss cheese. Reubens have become best-sellers at Katzâs, but when Alan Dell was young, it was unthinkable that a Jewish deli would serve meat and cheese together.
âEnough people started asking for it, customers, regulars, people we know and liked,â Jake Dell said. âItâs not like we were going to take away the old stuff, but we could add a Reuben. The same thing happened with a pastrami Reuben. For some reason, everyone wants a pastrami Reuben now. Weâre in the business of pleasing.â
In a typical week, the counter staff goes through 20,000 pounds of meat, half of it pastrami; 3,000 to 4,000 hot dogs; and 12,000 pickles. But the makeup of the staff has changed over the years. âIt used to be Eastern European Jews, mainly from the neighborhood,â Jake Dell said.
Now, he and his father said, the employees behind the counter and in the kitchen tend to be from the Dominican Republic.
Katzâs has become a survivor in a neighborhood that had long-established delis. It began 125 years ago under a different name, Iceland Brothers. They took in the first Katz, Willy, as a partner in the early years of the 20th century. Eventually, he bought out the brothers and changed the name from Iceland & Katz to Katzâs.
The Dells, who bought into Katzâs in 1988, say the first big change came in the mid-1940s, when the restaurant, originally on Ludlow Street, expanded, taking the corner storefront at Houston Street. The new storefront needed a new sign. âThe sign maker asked Harry Tarowskyâ â" one of the owners at the time â" âwhat he wanted on the sign,â Alan Dell explained. âHe said, âKatzâs Deli. Thatâs all.ââ The sign arrived with those four words on it, and has been in the front window ever since.
Nowadays, the crowd at Katzâs includes tourists who have discovered the Lower East Side â" Jake Dell says that New Yorkers âdonât necessarily eat in the store. They take it with them or they get it delivered.â And as the neighborhood has changed in recent years, one refrain at Katzâs has the rumors that it was for sale. âItâs not,â Alan Dell said. âItâs history. You donât sell history.â
Another refrain has come from what Mr. Dell calls âre-enactors,â people who recognized Katzâs as the setting for the scene in the film âWhen Harry Met Sallyâ in which the punch line is âIâll have what sheâs having.â
It was probably no surprise that Katzâs made a cameo appearance. âBilly Crystal and Rob Reiner are regulars,â Mr. Dell said, referring to one of the stars of the film and its director.
âBut our name was not listed in the credits, and unless you knew, unless you recognized it, you wouldnât know,â he said. âWe didnât see a measurable increaseâ in business as soon as the movie was released, he said, but later articles that mentioned Katzâs âput us on the map.â
But perhaps not the way he expected. Consider a segment he videotaped with Sherri Shepherd, a co-host of the daytime talk show âThe View.â
âShe starts recreating the scene,â Alan Dell recalled. âThe director, who was sitting out of range, said, âLook surprised.â He really didnât have to say that. I donât get uncomfortable easily, but that oneâ¦â
His voice trailed off, uncomfortably.
