The eagerly awaited moment has arrived: In-N-Out Burger opened in Round Rock on Tuesday, December 3rd and the response was nothing short of ecstatic. This is the first In-N-Out location in Central Texas to open its doors for business after the burger chain made their first Texas debut in the Dallas-Fort Worth Metroplex in 2011. Long lines of people and cars offer a warm welcome to the family-owned business and are likely to continue until excitement calms. The expansion will not end here. Both Austin and Cedar Park are expected to have locations open by the first of the year, and San Antonio is rumored to be next in line.
