We recently had my mom's 90th surprise birthday party at the Sunny Palace. At first, the room that we wanted was already reserved, so the manager suggested their smaller room. We estimated that we would have about 80 guests - we were told the room could only accommodate 70. Well, the manager went above and beyond to see if he could accommodate 80 - safely and comfortably. If not, he was willing to set up additional seating. It worked out that we were able to get 82 guests seated - a little tight, but it was better than setting up tables outside the room.
The manager was also very patient and flexible when discussing the party menu - willing to switch dishes out, and making sure that there was enough food for the larger tables (15 persons).. The wait staff were also extremely helpful - adding additional seats, and taking care of all of our requests.
Overall the food was very good. If we need to have another party in NJ - this would certainly be our first choice.
Just a note: we picked this place because we are familiar with the food - dim sum and dinner.
