326 South Street was suppose to get a new tenant, an organic one! The old spot of Underground Market has caught the eyes of Eyal Aranya and Yoni Nadav who wanted to open O! Burger, a burger joint in the Los Angeles area serving only 100 percent certified organic food (everything from the buns, the sauce, vegetables, meat, ketchup, mustard, fries and salad dressing is organic). This would have been fine, if the O! Burger Aranya and Nadav were opening was the same as the L.A.-based store. As it stands, both O Burgers have nothing to do with each other, and Andy Soboil (the co-owner of the trademarked O! Burger in L.A.) assures us they are not part of Nadav’s venture. “Will definitely get our lawyers involved,” says Soboil. Nadav is the owner of Abuco Inc., the same company behind City Blue and Versace Jeans Couture).
