@Yolee I just dropped my Slip 42 Cafe into Strangerville in my Build Save, which is a vanilla game, and my sims were able to get a table, order food, and eat it. Actually fairly quickly.

The only issue I saw was one sim had to pee and went to the toilet about 5ish times, sat on it, flushed washed his hands but never actually emptied his bladder.

He is paranoid so don't know if he has issues with public restrooms, but I never saw this happen before. Finally he went to the kitchen and peed on himself, drank his Alien drink and went home.
