The U.S. Embassy in Sofia issued a security alert Tuesday saying the city's gentlemen’s clubs should be avoided. Generally, security in the country has been better for tourists and business travelers since the country joined the European Union.
Earlier this year, the embassy issued a crime report that mentioned several incidents of club patrons being roughed up after refusing to pay outrageous fees for drinks and private dances in Sofia’s strip clubs.
