I think the current price is around $125 per person for 5 courses. If you want to do the wine pairing, that's another $60. Plus they usually have some extra courses, like caviar or foie gras, that you can do for an additional cost.
I've been there 3 times and I honestly can't tell you how many tables there are. It's pretty small, I'd say maybe 12-14 tables. It's a very quiet and intimate space, mostly couples dining for that special romantic evening. We went once as a party of 6 and I know we were the largest party there for that seating (they have 2 seatings per night).
Reservations are done separately than for the other Disney Dining and I'm sure that they'll be able to tell you the max per table. I'd honestly like to know too and was planning to check when we dine there in May because next January, there would be 10 of us and I'd like to go but I'd want us seated together.
And welcome to the boards.
