Omoide Yokocho roughly translates as Memory Lane - or, in other words, a place that you know from way back and feel somewhat nostalgic about.
Current Omoide Yokocho food stalls still trace their tradition back to the wild spirit of the old black market era of yore - though they are all properly licensed restaurants now.
