KOi Fusion to Pop-Up New Locale?

In a Tweet part cryptic, part Where's Waldo?, Bo Kwon's Korean BBQ food-carts-slash-restaurant KOi Fusion hints that a new location for its pop-style of serving is imminent. KOi's first sit-down site, Koi Fusion @ 1 in the Pearl District, will also unveil a new happy hour menu beginning today, but we're too busy salivating over a second pop-up possibility. Have a guess to what 'hood it's in? Spotted it somewhere around town? Send us a tip...
