PAIN incoming... The photo Natalie posted on 6/15/18 shows a plate with the logo of Le Pain Quotidien (Thank you @CaptianDissention for tracking this down). There is a LPQ located at 666 Pennsylvania Ave SE in DC.

Best translation I have is it means "The Daily Bread" - which is a phrase in The Lord's Prayer, and mentioned in drop 154 and 307.

Hmm 154 also mentioned the date 11/4 - wonder what starts then...
