Happy to see this question.  We frequently do the Alaska cruises and was wondering about ISP.  My eldest son always insists on Tracy's (last September was $95 for 2 legs and 2 beers).  This year an excursion in Juneau makes it sort of hard.  Have never had crab at ISP, so it will be worth a try for us while the others zip line.  Glad to see they have King for him, I will take the Dungeness.  Thanks everyone
