Canter's Deli in Los Angeles' Fairfax District. This massive restaurant looks exactly like it forty tears ago as a child, with it appears some of the same waitresses. Restaurant has been in the current location about 55 years, and in L.A. since 1931.
What's cool is after the bars close, Canters becomes a hangout for the "rockers", until near dawn. Total contrast to the daytime crowd, which runs the gamut from business people to the elderly.
Above average deli food and take-out counter to boot!
