Many thanks to @AllenEdmonds for sharing a photo of Keanu Reeves on twitter!
The tweet thanked Keanu for stopping by between takes. Considering his hair has been cut and the beard gone since early July, it more likely that he stopped by the store to get shoes and other items for either the film or personal use when he first arrived in New Orleans. Regardless it is a great photo and it is here. For those who are interested the store website is here.
