In this interview with Francis Lam, Grant Achatz drops some clues as to what the menu at Next might look like in the near future:
Chef Dave is really inspired by a children’s book right now, and our next menu can be entirely built on that. Or we can be an exact replica of another time and place. One menu might be from my memory: My first day at The French Laundry. It comes down to trying to be expressive. You can be expressive with a plate of food, or with the whole concept of a restaurant.
Another menu we’re planning is El Bulli. One course from each year from 1983 to 2003. I’d work with Ferran [Adria] to choose the dishes that he feels are his most significant; I’d need to get him on board with that.
