Columbus-based Cameron Mitchell Restaurants will open an Ocean Prime location — its 13th — in Washington, D.C., next week. Days before the doors to the G Street restaurant open to the public, though, Cameron Mitchell himself will give a special preview to about 80 VIPs. Among them will be Washington-based meeting planners and association executives who Columbus tourism officials attending the event hope will get a taste of what Columbus has to offer.adcelannotate = {"mobilepaywallcategory" : "MOBILE_PREM-BUSINESS","nativepaywallcategory" : "NATIVE_PREM-BUSINESS"};
