Here's a link that hopefully will answer most of your questions:

1. How much is it? We did Goofy's Beachfront Breakfast on Saturday, January 8, and it was $16.99 per adult (not sure about a kid price, as the only one we had was under 3 so she was free), plus tax and tip of course.
2. Is it worth it in your opinion? Absolutely, in our opinion. It was January so your experience in September may be different, but we had 8 a.m. reservations and there was only 1 other table full in the whole place. Goofy and Donald were so lonely and bored that they spent a huge amount of time with our granddaughter, and she was able to play and interact with them quite a bit. They even each came back a second time! I'm sure timing can make a difference, and it may have been busier later in the day, but we had the place to ourselves and it was great!
3. Do you have to make advanced reservations like you do at WDW? They say reservations are recommended, and we did make them, but, as I said, in our case it wasn't really necessary. If we did it again, though, I would still make reservations just to be safe.
Have a great trip! And I would definitely recommend checking out the Sunday brunch if you can as well. The selection, quality, and quantity of the food was fabulous. We will definitely be repeating this every chance we get. A very gourmet spread and I think it was still only $19.99 per person which I thought was a good value; it even included your choice of champagne, mimosa, or bloody Mary.
