TGI Friday's (often shortened to "Friday's" in most countries, previously stylized as "T.G.I. Friday's", and stylized "FRiDAY'S", or "T.G.I.s" in Ireland and the United Kingdom) is an American restaurant chain focusing on casual dining.
The company is a unit of the Carlson Companies. Its name is taken from the expression TGIF. The company asserts that it stands for "Thank Goodness It's Friday", although as of 2010 some television commercials for the chain have also made use of the alternative phrase, "Thank God It's Friday's." The chain is known for its appearance, with red-striped canopies, brass railings, Tiffany lamps and frequent use of antiques as decor.
