Far and away my favorite fast-food joint -- the only one I eat at, really. Must have a Taco Bell taco fix every now and then. And a bean burrito with green sauce.
In the early days, they had five items: Bean Burrito, Taco, Bell Beefer (taco meat on a bun), Tostada and Pinto Beans (can't remember if the cup of pinto beans had a special name). The menu also spelled out the pronunciation of each item -- Taco was Tah-coh, Burrito was Buh-rit-toh, or some such -- as "Mexican" food was not at that time mainstream enough for most Americans.
RIP, Mr. Bell.
