Please, proofread the sentence. I’m not sure about whether the tense is correct.
"At the moment, the “Korona” restaurant, which has been operated in the city is being expanded."
I’m trying to say that the Korona restaurant was opened some time ago and operates in the city. Now owners make it bigger to hold more visitors. What are the other variants to express the same meaning?
Thank you very much.
"At the moment, the city's “Korona” restaurant, which has been in operation since ..., is being expanded."
