Aqua, a fine-dining restaurant on Fifth Avenue South in downtown Naples, has added a new offering to its plate — an ultra-chic lounge with a 30-foot bar that can comfortably seat up to 80 people. Aqua offers Mediterranean-style seafood and steaks with open-air seating and a teak bar. Owner Gordon Stojkoski, a 31-year veteran of the restaurant and nightclub business, said he created the Aqua Lounge because of the demand. The new Aqua Lounge, which offers craft cocktails and boasts an extensive wine and champagne list, is open seven days a week featuring live music nightly and a happy hour with small plates from 4 to 7 p.m. Aqua’s expansion took over what previously was the adjacent Petunias of Naples women’s clothing store. Aqua, 862 Fifth Ave. S., also expanded its outdoor dining area, tripling the number of tables outside.
