As the PP said, you still have to check-in at the Elephant. The seating queue (inside the restaurant) is for when your table is ready. An ADR means you'll be next in line for a table for your party size (behind the other ADR folks that checked in before you), but it's not a reservation in the traditional sense (where the restaurant holds a table for you so it'll be empty when your reservation time rolls around). So even with an ADR, there is still the potential for a long wait after you've checked in...it all depends on how many guests are ahead of you in the queue.
