Philadelphia may be the fifth-most-populous city in the United States, but when it comes to romantic restaurants - well...

OpenTable, the restaurant-reservation service, puts Philadelphia in 15th place on a list of the Top 25 Most Romantic Cities in America.

San Antonio, Texas, was No. 1 for the second year in a row.

Atlantic City was No. 4. Guess that "Always Turned On" ad campaign really paid off.

The OpenTable Most Romantic Cities Index is calculated using three variables:

• The percentage of restaurants rated “romantic” according to OpenTable diner reviews

• The percentage of tables seated for two

• The percentage of people who dined out for Valentine’s Day last year

“Throughout history, love, food and romance are inextricably tied together,” said Caroline Potter, chief dining officer of OpenTable.

“When we looked at the connection between the number of diners seeking to share a romantic meal and the array of area restaurants offering intimate dining experiences, the data clearly pointed to these as the top cities in which desire is celebrated over dinner.”
