Yesterday, NW sent us an e-mail informing us that they had decided that a 1640 arrival was way too early so the new schedule for May is 1814. Based upon your first posting, it looks like we will arrive too late to attend Friday's planned event.
If this is not the case, please provide the address of the restaurant since there seem to be three KC locations. Also, a PM with a cell number would be appreciated. Lack of local knowledge.
