Try the Shrunken Zombie Head drink and the Ahi Tuna Poke. Divine!
I disagree that the area outside for the bar is large--I think it is actually quite small--we had to wait about 30 minutes to get a table to accommodate four people while the singers/guitarists were performing. There are maybe 6 tables and three or four couch/lounge/coffee table type set-ups. I really wish they had made the entire area a bit bigger. From what I have seen, the outside seating for Tangaroa Terrace (which is large) is not used to full capacity--they could easily expand the Trader Sam's area since they only do bar service within the Trader Sam's designated area (although you can go up to the inside bar and order a drink "to go" and take it over to Tangaroa Terrace).
