Seattle,Nashville, Oklahoma

Ok for those of you that read this but fail to comment or reply back now is your chance, I have been given the choice of where I, my supervisor and another co-worker can go to attend a training seminar for work, the choices are of Oklahoma, (which I have only driven thru a small part of the stat)e at a Tribal Casino but I am not a gambler so this don't turn my crank, to Nashville, which I was just at back in May for another training seminar, or my old stomping ground of Seattle, and I do confess I miss Iver's homemade clam chowder and deep fried salmon, fresh redhook from the tap, and Pikes Market along with Left ban Books, off the list is Greenbay which my supervisor stated I cannot choose, he has been there before and does not really care for the place. So any suggestions? Will it be Oklahoma, Nashville, or Seattle?
