For clarification, where Grand Case Boulevard ( the one way street ) intersects with the main road is Capt Frenchy's. Rainbow is two buildings further up the street - heading towards the lolos, and LTC Se Temp des Ceries, is a few doors further up. This photo is a few years old, but shows the layout
google aerial of grand caseI heard that the empty lot next to Frenchys was sold, and the owner plans to build a restaurant there .
