@@nattiegams325 & @@Shelleyq - There is a "Frequently Asked Questions" section that reads,
"Do my guests get to choose their own main course main course, for example meat or fish?"
"Yes, this is possible to choose from two options, however you should provide us in advance the number of each option, including a seating chart with the names of the guest, table number, and dish. Don't forget to bring your placing cards, otherwise this will not be possible. If you need help with this, please contact our wedding coordinator, she will provide you with a seating guest list and seating form."
I hope this helps!
