is this some kind of cafe

It's based off the "Meet Baroque Works" chapter cover series where Miss Goldenweek uses her paint to turn everyone into their dream forms. She becomes an artist, Miss Valentine becomes a baker, Ms. Merry Christmas turns into a princess, Sir Crocodile becomes King of the Pirates, Mr. 4 turns into a Pizza Deliveryman, Mr. 1 turns into a superhero, and Mrs. Doublefinger reverts to her Paula identity.

I can't quite remember what Lassiu, Mr. 3 and Mr. 5 become. Mr 2 evidently stays as-is.

Lasso became a tank lol.
