The episode received positive reviews from critics, who praised Cerveris' performance, Bruce's character development as well as Gordon and Pyg's fight.
Sofia (Crystal Reed) prepares for a fundraising event when she is visited by Cobblepot (Robin Lord Taylor), who is angry at Gordon being promoted as GCPD Captain and sets to find the person who authorized it as the Mayor is currently missing.

In October 2017, it was announced that the guest cast for the episode would include Michael Cerveris as Professor Pyg, Gordon Winarick as Tommy Elliot, and Christopher Convery as Martin.
Matt Fowler of IGN gave the episode a "good" 7.3 out of 10 and wrote in his verdict, "'Let Them Eat Pie' was notable for Pyg's dinner scene and the insanity that ensued (including song & dance, meat pies, and his showdown with Jim), but the character's over-the-top schemes, and psycho butchery, don't match up with his blasé quest to end city corruption.
Gotham has told its more compelling stories in the build-up to this episode, and 'Let Them Eat Pie,' partly out of necessity, is focused solely on catching Pyg.

"[9] Lisa Babick of TV Fanatic gave the series a 4 star rating out of 5, writing "Jim's first day as Captain was a blast on Gotham Season 4 Episode 9.
"[5] Marc Buxton of Den of Geek gave wrote, "Thankfully, Gotham saves the day with a pure gross out, surreal bit of business that features a dude with a pig head singing while feeding homeless people to rich folk, and it's stuff like that that sets Gotham apart from the countless other comic book shows on TV.
