I have varied memories of Mayfair Games. While their Dark Folk adventure book was a supplement I went to numerous times, their City State of the Invincible Overlord boxed set was... lacking, But their Demons series was top notch and their Underworld RPG wasn't bad. Wasn't Chill under their label for a bit?
In any case, the shop is now closed:
