There is no Cracker Barrel further West than Boise, so no, no Cracker Barrel in Los Angeles. Your loss. I reject your definitions of "major city" if it wouldn't include metropolitan areas as large as Chicago and Dallas-Fort Worth, which is the third and fourth largest in America and each of them home to Cracker Barrel.

There's Cracker Barrels in upstate New York and New Jersey as well, if you get out of Manhattan.
