A favorite among south JoCo cougars, white-collar businessmen and the up-and-coming stiletto-and-loafers set, RA Sushi can turn the nigiri-and-martini experience into a blood-pumping, pheromone-emitting shark tank not for the faint of hormone. Those on the prowl can hide behind their small plates of thinly sliced sashimi and Viva Las Vegas rolls only so long before the lights go down, the bass from the DJ starts kicking, and the $9 Shiso Naughty martinis (made with Skyy Pineapple vodka and X-Rated Fusion Liqueur) start flowing. It's what Kona Grill used to be when college grads were moving to the Plaza instead of back in with their parents. The best part? Affordable rooms are usually available upstairs at the Aloft Hotel, making the encounter all the more trendy, upscale and convenient.
