On our way back from La Isla (of which more soon), we saw a billboard that was more of a threat than any billboard I can recall, telling us that the ONLY place to eat at Guy's Burger Joint was on a Carnival Cruise ship. To put it in a more upbeat, glass half full kind of way, all you have to do to avoid Guy's Burger Joint is to continue your sensible policy of avoiding Carnival Cruise ships. Would that all problems were so easy to solve!
You can peep the menu here, which is impressively concise, compared to the infamous Times Square Fieri jawn. That said, both "donkey sauce" and "rojo ring" somehow take on an ominous connotation at sea.
