"Do you play tennis at the old department store?"

Translation: A régi áruháznál teniszeztek?

I guess that 'A régi áruháznál teniszezel?' needs to be accepted, too.

[bdori]

yes, it's a correct translation, too

[MilosVlahovic]

Reported.

Do you can also be singular, however it's not accepted.

[_paranoia_]

I think this sentence should actually be translated as "A régi áruházban teniszeztek", which doesn't actually make that much sense. "By" or "next to" would be more appropriate than "at", here.
