i can talk about the moist, aggressively spiced blackened chicken. i can talk about the melted, gooey, sharp jack cheese. i can talk about a million things under the island palm trees, but i won’t, because i’ve temporarily lost my voice. why? because my tongue is singed and my tonsils are shriveled, all courtesy of the jalapeno peppers and the habanero chili coating applied to duke’s churasco at the tiki-themed Island Burgers & Shakes. i am proud to say that i finished this ‘wich in one sitting. i am less proud to say that there were many unpleasant “sittings” as a result of that culinary foolishness. something tells me that duke was never that merciless. so much for the aloha spirit.
