The Westin Tampa Bay hotel has purchased the AquaKnox restaurant on its ground floor from E-Brands Restaurants. A purchase price was not released. The Westin will operate the restaurant as AquaKnox "for the short term," a press release said Friday. Restaurant staff and management will remain. Tavistock Group paid $11.3 million last week to acquire Orlando-based E-Brands out of Chapter 11 bankruptcy. E-Brands owns another AquaKnox in Las Vegas and Timpano Italian Chophouse restaurants in Tampa, Orlando, Fort Lauderdale and Rockville, Md.
