The Hat is a Southern California fast-food restaurant chain specializing in pastrami dip sandwiches.

[1] This eatery, once local only to the San Gabriel Valley,[2] has been offering its "World Famous Pastrami" to Southern California residents since 1951.

[5] The original Hat Restaurant was located at the intersection of 3rd Street and Ford Boulevard in Boyle Heights (now known as East Los Angeles).

The current company has kept to its roots by keeping its retro neon signs featuring a chef’s toque and the words "World Famous Pastrami”.

[2] The Hat offers no table service, so all of the items are wrapped to go, but paper plates are given to customers who wish to "dine in."
