I sent a message through Yelp requesting their new temporary address and received this reply from "Eugene L:"
“Hi Gary, thanks for reaching out. Our temp location will be at the corner of Broadway and Columbus, not too far from the original location. I can get the exact address for you later once I confirm with Chef Nei. Are you looking to make a reservation? Thanks -Eugene”
The four actual corners of B'way and Columbus are "taken" (The Condor Club, E Tutto Qua, Nizario's Pizza and New Sun Hong Kong), so I'm guessing it might be the Cookhouse event space above Vesuvio's (corner of Columbus and Jack Keroiuac).
