Even if your boo cringes at the thought of anything nature-oriented, she'll be a sucker for the baby animals strolling on grassy knolls at the Bronx Zoo.
If baby animals aren't her thing (Seriously? What kind of woman is she?!), take a stroll through the butterfly garden, peep monkeys, giraffes, tigers, and even lemurs (as part of their Madagascar exhibit) and feed penguins and sea lions. Ambling along the LEGO Wild Forest, a special exhibit that features realistic renderings of the zoo's animals, is also a must.
End your excursion into the great outdoors with the Wild Asia Monorail, a 20-minute ride in the sky that gives you a bird's eye view of the best exhibits (that are often too crowded to see otherwise) and the Bronx River, and affords an opportunity to steal a kiss in the sky. Damn, you are one slick dude!
