Margaret Primrose

 runs the Cafe Beau Monde in Tenpenny Tower. She offers food, beverages and a few stimpaks. If asked how the Ghouls living nearby would like her food, she replies "I never thought about that." and changes the subject.

Sometimes, when engaging Margaret Primrose in conversation, she will start by saying, "Sit anywhere you want, except for that table in the corner. That's Mr.Tenpenny's table." This further suggests that Allister Tenpenny is an important person in this tower, considering he owns it.

In an NPC to NPC conversation Herbert "Daring" Dashwood will compliment Margaret Primrose's cooking. She will then say that the shop is running low on food supply, but that just makes her more creative.
