The popular Dale Carnegie book, "How to Win Friends and Influence People," offers a plethora of helpful tips to do just that, but we caught an oversight, there is no mention of tacos. Delicious and universally appealing, tacos can be a powerful shortcut to gaining allies. This is especially true if the tacos originate from Steven Arroyo's new concept restaurant, Esquela Taquieria. Arroyo elevates the classics with his branzino fish tacos, spicy habanero cole slaw, organic duck tacos and perfectly charred eloté. While you may think it's ridiculous to spend $6-$8 on street tacos--and maybe it is--allies can be very useful (just consult your history books).
