When a newly opened coffeehouse in a notoriously dead commercial block is packed with patrons every weekend night, something must be brewing right. Nearly a year into business, Coffee Code rests in the shadow of Knott's Berry Farm just before the intersection of Beach Boulevard and La Palma Avenue. Don't make the mistake, though, of showing up there for a caffeine jolt before heading on your morning commute: The establishment opens at 11 a.m. and closes at midnight. Its strong point is its broad menu of drinks that don't hit the wallet too hard. The Eiskaffe is the most popular of its signature creations. Order it, and a server will bring you a scoop of vanilla ice cream in a coffee cup, pouring a potent espresso over it. The sweet-potato latte also beckons the curious. There's a wider array of choices for the noncaffeinated than at most such establishments. The green-apple slush tastes like a syrupy, liquefied Jolly Rancher, perfect for those who don't want to stay up until all hours of the night staring at the ceiling. For the sake of decadence, add a dessert, such as the whip-creamed waffles. As a coffeehouse, Coffee Code wins presentation points for both latte art and ambiance. Korean pop playing from a mounted flat screen sets the mood; a cushy couch is the best seat to secure in the house. If its popularity keeps rising, Coffee Code might think of expanding to the empty Papa John's building next door, ending the commercial block's reputation as dead weight for good. $
