While investigating a different part of the French revolution, I came to the following conclusion:
Until October 6, 1789, the National Constituent Assembly met in the Hôtel des Menus Plaisirs, Versailles. October 6, 1789 and onwards, the National Constituent Assembly met in Salle du Manège, Paris.
Therefore they met in the HΓ΄tel des Menus Plaisirs on August 4, 1789.
