i believe you are right...i know that the l'atelier in tokyo (roppongi) had it and i had a long conversation with my server about how I couldn't get it in the US. in the end, my server insisted that they had it at the NYC l'atelier.
ippudo will be opening on 4th ave later this fall. i remember in tokyo they were open till at least 4 am. hopefully the manhattan outpost will be the same.
