Chinatown restaurant for a big family meal?

Still pretty new to Philly, but my partner and I are getting married at city hall next month. All of our immediate family will be visiting for dinner after.

Whenever we normally visit my partners family we have a traditional Cantonese dinner at a restaurant his father picks.

Ideally looking for a restaurant that works for 10-15 people. Offers traditional food and vegan options. And possibly a private room but that’s not essential.

Any recommendations would be appreciated.
