similar to those in the US, and the same big two chains dominate the High Street as in the U.S. — McDonald's and Burger King. The menus offered to both countries are virtually identical, although portion sizes tend to be smaller in the UK. In Ireland, the food outlet Supermacs is widespread throughout the country, serving burgers as part of its menu. In Ireland, Abrakebabra (started out selling kebabs) and Eddie Rocket's are also major chains. An original and indigenous rival to the big two U.S. giants was the quintessentially British fast-food chain Wimpy, originally known as Wimpy Bar (opened 1954 at the Lyon's Corner House in Coventry Street London), which served its hamburgers on a plate with British-style chips, accompanied by cutlery and delivered to the customer's table. In the late 1970s, to compete with McDonald's, Wimpy began to open American-style counter-service restaurants, and the brand disappeared from many UK high streets when those restaurants were re-branded as Burger Kings between 1989 and 1990 by the then-owner of both brands, Grand Metropolitan. A management buyout in 1990 split the brands again, and now Wimpy table-service restaurants can still be found in many town centres, whilst new counter-service Wimpys are now often found at motorway service stations. Hamburgers are also available from mobile kiosks, commonly known as “burger vans,", particularly at outdoor events such as football matches. Burgers from this type of outlet are usually served without any form of salad — only fried onions and a choice of tomato ketchup, mustard, or brown sauce. Chip shops, particularly in the West Midlands and North-East of England, Scotland, and Ireland, serve battered hamburgers called batter burgers. This is where the burger patty is deep-fat-fried in batter and is usually served with chips. Hamburgers and veggie burgers served with chips, and salad is standard pub grub menu items. Many pubs specialize in "gourmet" burgers. These are usually high-quality minced steak patties topped with things such as blue cheese, brie, avocado, anchovy mayonnaise, et cetera. Some British pubs serve burger patties made from more exotic meats, including venison burgers (sometimes nicknamed Bambi Burgers), bison burgers, ostrich burgers, and in some Australian-themed pubs even kangaroo burgers can be purchased. These burgers are served similarly to the traditional hamburger but are sometimes served with a different sauce, including redcurrant sauce, mint sauce, and plum sauce. In the early 21st century, "premium" hamburger chains and independent
