We took our Belgian/Italian friends to a Chinese dinner in 2015 in the 9th. Not likely the same, but similar to your description.
My friends were the only non-whites in the restaurant. Seemed the greater percentage were Mainlanders. The couple sitting next to us were Chinese from Las Vegas.
Do you know this restaurant, is it still alive? I think the name is etched on the service, I can’t make it out on my phone.
The food was quite good. We were quite surprised that our guests ate and enjoyed it all, peppers and all. They actually really loved it.
