Well, I think I would agree that the idea of a restaurant with rats and cockroaches would be pretty unacceptable.  I know that those are “unpleasant creatures”, and I’m not particularly fond of them.  But I wouldn’t really be concerned about the restaurant’s cleanliness or whether there were cockroaches there, so from that perspective it seems like the restaurant could be as dirty and unhygienic as it wanted, as long as it didn’t serve food and kept the rodents out.

Hmm, the word “acceptable” is a little ambiguous here.  To some extent, I’d say that “acceptable” means “permissible” or “legitimate”. So, depending on how your criteria for the “acceptability” of a restaurant is set, the presence of rats and cockroaches might be “acceptable”, or it might be “unacceptable”, or it might be something in between.  Do you want to set a specific criteria for “acceptable”?

Is it okay for a restaurant to remain open if it has rodents and cockroaches?
user
Hmm, I think that would depend.  Let me tell you what I’m noticing in the context of the question: There’s a place called the “Restaurant”, and it’s associated with rodents and cockroaches.  And we’re also asked whether it’s “okay” for the restaurant to remain open.  Given the strong associations between rodents and cockroaches and how disgusting they are, it seems possible that “okay” here could have a meaning along the lines of “tolerable” or “unsatisfactory”.  So in that case, I could imagine that the most likely meaning of this question is something along the lines of “Are there any situations where it would be acceptable for a restaurant to remain open even if it has rats or cockroaches?”
assistant
Yes. That's what I'm asking.
user
I see. So, from your viewpoint, it would be acceptable for a restaurant to remain open even if it had rats and cockroaches?
assistant
I'm not sure. Would you say it would be acceptable?
