Hi Jinny,
I found a few actually: Yang Sing in Manchester do catering - but we've just cancelled them as we agreed a price and they then turned around and wanted to add an extra cost of £1k-£2k....couldn't give me an exact total as they "forgot" to add on vehicle hire....full of crap - more like they wanted to make money out of us!! Their food is nice but I would be careful as they don't stick to their "word"
We're still in talks with Leigh house but not been down to the restaurant yet.
We also found a few other authentic Chinese caterers but need to see them first before committing to them.
I'll keep updating the post
