We’re not doing it this year, but several years we have gone to Main Street Grill here in Round Rock on Valentine’s Day.

They have a special menu for the night, and it’s reservation-only. Pay a set price per person, then choose from the limited menu.

Works out great, and we always had a great meal. It must work for the restaurant, too, because they offer it every year.
