. The Ocean Journey aquarium was not able to make payments on its high construction debt, and filed for bankruptcy in April 2002 with a $62.5 million debt. Landry's Restaurants, Inc. purchased the facility in March 2003 for $13.6 million. After the purchase, the facility remained open to the public until the summer of 2005, when it closed briefly for renovations. These included the addition of a full-service restaurant, bar, and ballroom. A marine aquarium was added to the restaurant area. Upon its reopening July 14, 2005, the facility was renamed Downtown Aquarium. On February 14, 2024, a person was shot and killed outside the aquarium.,
