That "better flavor" lime juice can go into one of the bar's mugs but those who are really into tiki culture could buy their own from a collection of only 40 customized mugs made for the bar for $333. That big cost also gets special mug owners into the Tiki Underground Syndicate. Those in the group will get special invitations to test new drinks, a Tiki Underground shirt and the preference to reserve tables for events hosted by the bar.
