The 12 rules for not getting in trouble at Katz's Deli

If there is an official deli season, it's right about now. It's also full-on tourist season in New York, which means that the lines at Katz's Deli are going to become even longer than usual. Jake Dell, the 29-year-old (truth) owner of Katz's, talks like he's a 75-year-old deli guy and has strong opinions about how to behave at his deli — and every classic Jewish deli. (In fact, he grew up at the place; his grandfather, father and uncle officially bought it almost 30 years ago.) He wants you to know what they are. Because he's not afraid to kick you out.

"My true New Yorkers, my die-hard Katz's fans, know that we serve the best hot dogs in the city. We are consistently rated as No. 1 in the hot dog department. There's a reason for that: We make them with all-natural beef and crispy casing, and they're juicy in the center. So get a hot dog first. Then, while you're waiting for your pastrami, you eat your hot dog — it's the perfect app. And there's only one way to eat a hot dog, with mustard and sauerkraut. None of that Chicago dog nonsense: no relish, no pickles, no salad garnish, no ketchup. Well, ketchup is OK — if you're under 6 years old. Don't hate me, Chicago. I was rooting for the Cubs, but you don't know how to eat a goddamn hot dog."

"I talk so much about pastrami, people often tell me to shut up. But if you come into my restaurant and order the classic pastrami sandwich and ask for it on white bread with mayo, I might not be able to stop myself from throwing you out of my establishment. I'm nicer than my grandfather, who would have actually done it. I might at least serve it to you, with a scowl on my face. Pastrami is meant to be eaten with mustard. No ketchup, either, though it's OK for French fries. I'm not thrilled about ketchup on our brisket sandwiches, but my grandmother would do it. I love her, so I'll let you order it, but it helps if you're an 85-year-old Jewish grandmother when you ask for ketchup with your brisket."

"We make our own mustard. It's spicy, deli brown mustard that is so phenomenal and pairs so well with pastrami and corned beef, and with knishes and hot dogs. When someone asks for yellow mustard, I say, 'You have mustard on your table.' When you look at a Crayola box, the crayon that's labeled as mustard is different than the yellow one. That's because mustard is supposed to be yellow-brown. So no yellow, not-real mustard with your pastrami, please."

"We designed Katz's so that you interact with the guys that cut the meat. You tell them, 'I want a little bit of this,' and they give you samples. It's 100 percent your right and your obligation and duty to say, 'I like this, I don't like this, I want it juicier, I want it leaner.' "

"Tell [the cutters] you want it juicy like Lucy. Juicy is where the fun is. Juicy is the sweet code word for fatty. No one wants to say 'fatty,' they feel weird. I'll say 'fatty' all day, and I'll say it when I go to a brisket joint: Fatty, please. But if you feel weird saying 'fatty,' say, 'I want it juicy,' and we know what you mean."

"When you say white bread, I think of Wonder Bread, which is — I don't know what it is. But it should be illegal. It's not sturdy — it won't hold up to a pile of meat, it will fall apart. I'd rather you get your sandwich with no bread. Rye bread is the best tried and true complement to a traditional deli sandwich. Look, I know everyone is now a foodie and an expert, but we've been around for 129 years, and we've learned a thing or two about how to make the perfect sandwich, which is pastrami on rye with mustard."

"One thing you might not know about Katz's is that I would put our turkey against anyone's. It's an all-white-meat, hot-turkey number, like Thanksgiving in sandwich form. It's what I eat most days because you can't eat pastrami every day. You can get gravy with it, and you can also do mustard. I frown on mayo, as you know, but I allow it on turkey — also lettuce and tomato. Turkey allows for a few more compromises than pastrami."

"If we're calling a spade a spade, a Reuben is not a real sandwich. No true Jewish deli would have had cheese [with meat], ever. So how could you make a Reuben without cheese? The short answer is, you can't. It's a fictional sandwich. That doesn't mean it's a bad sandwich. When people tell me that a traditional Reuben has corned beef and that I'm doing a crazy Reuben with pastrami, I say, none of them are traditional."

"My goal is to make the world's second best latke; your first should be made by a family member. Our latkes are based on an old family recipe: The potatoes are chopped, not grated, with a nice amount of potato inside, and they're crispy outside. Way back when —we're going back decades, generations — different family members competed to see who made the best one, and that's what we serve at Katz's. It's a fun family story, anyway: the mythical, epic battle of the bubbes. Personally, I'm sour cream with the latkes, but there's applesauce, too. No ketchup. It's not a hash brown."

"Here's my perfect Katz's meal: I would order a hot dog, half a pastrami, juicy, with matzo ball soup. With a side of latkes and maybe some French fries, if I'm feeling crazy. And if I can do it, I'm getting cheesecake, too. And if I've got a group of people, I'm splitting a knish, and putting a Reuben sandwich on the table, too. There's a lot more perfect meals you can do, depending on the size of your party."

"You might have read the stories. When you enter Katz's, you're given a little ticket: It's your check. It's a classic system, you don't see it anywhere else. You take it with you, as you go station to station. Even if you didn't get anything, we need it back so we know you didn't eat anything. We don't want to be a pain ... but when you serve 4,000 people a day, you need a tried-and-true system. Don't talk to me about updating with computers; we need that ticket. People who lost their tickets — they might still be washing dishes (I'm kidding) — we try to help them find it. But if it's gone, you have to pay a fine. So don't lose it."

"And while you're holding your ticket, know that there isn't one line; each counter has its own, so there are as many as seven lines. My regulars are very aware of this. If you're standing around trying to take pictures for your social media, don't get mad when people push past you. It's eye of the tiger here. Come hungry and be prepared to bring it, and we'll take care of you."
