In Episode 9 The Handmaid’s Tale revisited an area that has been used pretty extensively in the series, Main Street. This area is apparently very popular, as American Gods also used this same corner for a scene recently. The Handmaid’s Tale has actually used this area 3 times in season one, for a couple different shots.
