Brennan's French Quarters, Royal St., New Orleans
On the back it says that the building was erected during the twilight of Spanish rule of Louisiana, later it was the Louisiana Bank, the first banking institution in the Louisiana Territory. After that it was the home of Paul Murphy, world-famous chess champion.
But when we went there it was a French restaurant.
I do not know of any specific fact, but I'm sure when we dined there the expression faux pas was used many times.
