Rewarding projects completed by Richard and Casey Gonzmart include a 5,000-square-foot kitchen expansion in 2001 at the Columbia in Ybor City, which was founded by their great-grandfather. The new kitchen was built in what was a parking lot/delivery area on the south side of the restaurant. The Gonzmart’s made a close to $2 million investment in building the new kitchen to sustain growth at the restaurant and to keep pace with the city's growth.

​

The old kitchen space was remodeled and turned into two new dining rooms; the Andalucia and the Familia de Casimiro. These are the first new dining rooms built in the restaurant since 1956. The Familia de Casimiro was named in honor of Richard & Casey’s great-grandfather and the founder of the restaurant, Casimiro Hernandez Sr., and is designed to resemble a Spanish wine cellar, with space for private meetings.

​

The Andalucia seats up to 80 people, and the Familia de Casimiro seats up to 30 people. These two new dining rooms add an additional 110 seats to the restaurant, and bring the total number of dining rooms to fifteen, with seating for up to 1,700 people.
