I think they cater. I didn't see a private room. It's kind of an open concept .
I did not see a private room there, but you could probably push some tables together for a small group. Alternately, you could ask if they could cater at a different location. They do have a catering menu on their web site. https://lamadeleine.com
No private rooms and they don't do reservations, so having a large party will be difficult especially with how busy they get
