As mentioned RFC doesn't take reservations for dinner through the Disney website. You have to call to make the reservation and I highly recommend you do that (or join the Landry's Select Club for priority seating). The walk-up wait times can be very long (>60 minutes), especially on weekends. I've been there when the walk-up wait time for a party of 4 was 2 hours!
I remember when I first tried to make ressies here. I thought, SHOOT they're already booked!!! But then I realized I just have to call. Man, I can taste those MoJo ribs right now.
Thanks I guess I overlooked the note about dinner that makes me happy, I am hoping to convince my kids instead of Goofy's this time maybe Rainforest I hadn't planned on doing Goofy's since they changed the characters to set characters but my son had said he wanted to so hopefully a frog cup can convince him otherwise
