The term “chain restaurants” is modernly used to imply a series of scattered dining outlets, usually owned by a single restaurateur or umbrella company, beneath which franchises or subsidiaries operate. Fast food restaurants such as McDonald's and Subway are the most commonly attributed restaurant brands under the “chain” definition, however the meaning extends to even the multi-locational, steakhouse and ranch style restaurants of America, like T.G.I Fridays and Taco Bell. Chain restaurants tend to be of a similar character or theme, regardless of location. McDonald's, an omni-present global fast food brand specializing in burgers, fries and ice cream takeaway treats ensures the same products are available from all outlets, regardless of whether it is a drive-thru or sit-in store. In the U.K, Wendy's remained the stalwart competition of McDonald's for over 20 years! The largest varieties of chain restaurant brands are usually found within big tourism oriented cities – London, New York, Paris and Las Vegas being prime examples. A very recent addition to the staid offerings are fine dining restaurant chains, incepted by celebrity chefs with a cult national or international following. Wolfgang Puck (whom has been a familiar judging personality on U.S tv's “Iron Chef” and “Top Chef” competitions) owns an omni-present brand with pizzerias and trattoria style restaurants across 20 states. His establishments are considered a real American dining experience (despite the fact he is French) with the very real possibility of a celebrity sighting or two during your visit!
