if you are using vouchers(free with 10 day world ticket)and want character breakfast in a theme park try restrautosaurus in animal kingdom, we had micky,donald, goofy & pluto and it was excellent!
Sorry to say we had a terrible eperience of Restaurantosorus last year - using our free breakfast voucher. The service was terrible - I think due to the fact that the first thing she asked when we sat down if we were 'vouchers'. Character interaction was mimimal and felt as though we were being rushed out the door to accomodate the hordes of people outside waiting to get in. The food was merely ok - nothing special.
Sorry to be so negative - but we will never go back.
