A sanctuary of sweet treats, City Street Sweets packs a jellybean jar's worth of retro candies, decadent truffles, creamy fudge, chewy caramel apples, and more inside its fern-colored walls. Steal your valentine's four-chambered muscular organ with an Uptown Classic truffle eight-piece gift box ($11.95), teeming with gourmet truffles in flavors such as dark-chocolate raspberry, milk-chocolate caramel, and dark-chocolate champagne. Unbirthdays are best celebrated with a Birthday Cake fudge ($8.25 for 8 oz., $16 for 16 oz.), a vanilla-fudge box loaded with mini marshmallows, rainbow sprinkles, and expired birthday wishes. Sink your canines into a caramel-apple pie CraZapple ($11.95), cloaked in fresh-roasted pecans, white chocolate, and cinnamon sugar, or delve deeper into the den of decadence with an old-fashioned strawberry soda-pop float ($4.79), a Sprite sea awash with Titanic-sinking strawberry icecaps. The candy college at City Street Sweets keeps wandering minds occupied with an arsenal of chocolate-drenched course offerings. Channel your inner Einstein at the Chocolate Bar Inventor class ($11.95), in which students are paired with PhD-toting Oompa-Loompas to create an original candy bar bundled up in a wrapper of their own design. The Candy Jewelry Designer course ($16.95) transforms budding fashionistas into haute-couture bling designers with tricks to turn last year's Lifesavers into this year's must-have accessory.
