we have enjoyed the chef's table several times. it is worth the $$$ for us. my best advice is to be on the phone early on the 180 day to make the reservation. there is only one seating and it can go fast. good luck!
No - you still call 180 days out. They will then let you make ADRs for the first day of your vacation (first day of Disney resort reservation) PLUS the next 10 days. However, I don't believe Victoria and Albert's participates in the "plus ten" part anyway - they are strictly 180 days out.
