Same here, Siri solves this problem.

Me: “Hey Siri, how late is x open?”

Siri: One possibility is on x street, does that sound good?

Me: Yes

Siri:

“X is open from y-z.”

I just tried it and you're right, it works. Well, it didn't used to work so I stopped using Siri. I regret the error.

I wonder if people assume Siri failed to understand the query when they hear its request for clarification. I think it should include some context, eg: “Which x do you want opening hours for?”
