the actual patty, there are burgers made with Kobe beef, butchered from cows that are fed with beer and massaged daily. McDonald's Japan also recently launched a McPork burger made with US pork. McDonald's has been gradually losing market share in Japan to these local hamburger chains due partly to the preference of Japanese diners for fresh ingredients and more refined, "upscale" hamburger offerings. Burger King once retreated from Japan, but re-entered the market in summer 2007 in cooperation with the Korean-owned Japanese fast-food chain Lotteria. Denmark In Denmark, the hamburger was introduced in 1949, though it was called the bøfsandwich. There are many variations. While the original bøfsandwich was simply a generic meat patty containing a mix of beef and horse meat, with slightly different garnish (mustard, ketchup, and soft onions), it has continued to evolve. Today, a bøfsandwich usually contains a beef patty, pickled cucumber, raw, pickled, fried, and/or soft onions, pickled red beets, mustard, ketchup, remoulade, and perhaps most strikingly, is often overflowing with brown gravy, which is sometimes even poured on top of the assembled bøfsandwich. The original bøfsandwich is still on the menu at the same restaurant from which it originated in 1949, now run by the original owner's grandson. Following the popularity of the bøfsandwich, many variations sprung up, using different types of meat instead of the beef patty. One variation, the flæskestegssandwich, grew especially popular. This variation replaces the minced beef patty with slices of pork loin or belly and typically uses sweet-and-sour pickled red cabbage, mayonnaise, mustard, and pork rinds as garnish. Today, the bøfsandwich, flæskestegssandwich, and their many variations co-exist with the more typical hamburger, with the opening of the first Burger King restaurant in 1977 popularizing the original dish in Denmark. Many local, high-end burger restaurants dot the major cities, including Popl, an offshoot of Noma. Other countries East Asia Rice burgers mentioned above are also available in several East Asian countries such as Taiwan and South Korea. Lotteria is a big hamburger franchise in Japan owned by the South Korean Lotte group, with outlets also in China, South Korea, Vietnam, and Taiwan. In addition to selling beef hamburgers, they have hamburgers made from squid, pork, tofu, and shrimp. Variations available in South Korea include Bulgogi burgers and Kimchi burgers. In the Philippines, a wide range of major U.S. fast-food franchises are well represented, together with local imitators, often amended
