Shake Shack is also meh. Fries reminded me of those or'ida fries the parental unit used to make in the oven on a cookie sheet. Shiny counters and good PR is all I saw.
FWIW the shakes were AWFUL (had those ice crystals that form similar to "frozen ice-milk drinks"). They aren't even in the same food group that Chick-fil-a shakes are in, and CFA shakes aren't even in the name.
Best burger in FLL is at "Lil Reds" next to the airport. Fat burger, cooked the way you want it (they don't force you to cook it to "briquette" or "remaining carbon residue"), on Texas Toast. Nice and runny.
Leave the rabbit food off. Just ketchup/mustard, which mixes with the beef grease to congeal with the toast to form a pleasing doughy pink goo around the meat itself.
Side of red beans....ahhh, Heaven.
