Pen knows about the magic restaurant! You can go in it, and get food or things to drink (she has bracelets!) and then you just go back out the door and it's been no time at all and you're right where you went in.
She goes in. She is going to have cake.
There is a friendly looking man sitting at the bar. He is currently having what might possibly be the most fluffy, decorative piece of chocolate fudge cake the world has ever seen. It's got multiple colors of frosting, sprinkles, and some raspberries, among other things. This isn't the only thing he's having, he's quite a big eater, but the cake might be the most relevant to the little angel's interests.
Suuuuch cake!
Pen' hops up next to him at the bar, wings fluttering with excitement and for balance, and waves her bracelets and exclaims, "That cake!"
And then she has a slice of that cake.
"Hello there," he says with a smile. "I'm glad you approve of the cake."
"Is pretty," opines Pen, and she eats a big forkful and nods and adds, "is sweet!"
"It's both indeed! This is an interesting place - I've never met anyone with wings before," he says. That's a lie, actually. He has a pair of wings, and his entire family has the same. But, he's in disguise, he has to keep up the persona.
"I angel," explains Pen. "Like Mommy." She notices him looking at her Kiss, and checks him for one, and finds none, and nods to herself.
He wants to visit. Probably not looking like this, he'd change up the illusion so he looks like a different human, maybe a girl, but he wants to see. Humans are fascinating little creatures. Seeing what they do with wings would amuse him for decades, at least.
Pen laughs at him, and eats a big forkful of cake. "Door does magic door. Goes worlds, hides with other door, surprise! Bar!"
"Such lots," says Pen. "And Daddy too. And two more Dars and one more Keziah and one more Ariel. Only one me anywhere, now!"
"I see. So what's it like, at your home?" asks the man. He's trying to get a good picture of it - it's sounding like they bear more similarity to his species' dynamics, instead of humans', despite the visual similarity.
"I live in Eyrie. Many many angels, always sing songs. Mommy leading host is important and she will Archangel."
Pen looks confused. "Only have one is my Mommy. Others are other ones of Mommy."
"I live Samaria," says Pen. "Other ones from other worlds. Look like Mommy except wings and stuff, sound same except Mommy best singing, like that. Same with ones of Daddy or sisters. My mommy and daddy only ones having four kids, so, one Pen, but more others other ones had."
"... There are multiple versions of your mother? And your father?"
