This must have been a pretty big shock for the employees at the SeaShell of Lisson Grove in London when Lady Gaga came walking in.
The singer's dressed for the occasion wearing the restaurant's namesake in her wild weave, which was also adorned with some other sea creatures.
While it might be a surprise to see one of Forbes' wealthiest celebrities in a fish & chips place, this actually isn't out of character for Gaga, who admits that she doesn't like to "live like a rich person" because it inhibits her creativity.
Of course, if the restaurant knew Gaga was on her way, they probably would have picked up the basket of french fries....er, chips...that was dumped on the floor near her feet, but knowing Gaga, she probably didn't even give it a second thought.
Before Gaga went to bed, she tweeted, "Had a LOVELY time w/ UKmonsters last night I recognized many of u, gorgeous!" and posted an Instagram snap of herself in bed with the caption, "Night night London. Thank u for the yummy sea treats :) Me and Karl are going sleepies xxo."
Mother Monster is, of course, referring to the Karl Lagerfield doll that she's holding.
Hopefully she got a good night's sleep, as she needs her rest for the iTunes Festival on Sunday!
