This classic New York deli serves up enough pastrami to feed an army.

Katz's Deli is frequented by regulars who've been coming for decades, as well as tourists and neighborhood newbies; occasionally, you might catch a glimpse of a celebrity. Since its establishment in the 1880s, the deli has changed very little in appearance, retaining a grungy sheen. Grab a ticket on the way in for counter service, or seat yourself at a table to be waited on. Katz's still makes about 5,000 pounds of corned beef, 2,000 pounds of salami and 12,000 hot dogs a week--the old-fashioned way, on the premises--and it shows in the massive portions the deli serves. Excellent pastrami is a big draw, as is the deli's Reuben sandwich.
