We have good news, great news and, then, bad news. First, the good news: The Pontchartrain still exists, even making it through the looting and vandalism of Hurricane Katrina. It stands, it operates and it preserves its late 1920s history as best as possible (it first opened in 1927).
The great news: even the Caribbean Room still exists, though it now functions as more of a dining room than a rollicking evening out destination. The cuisinedescribed in the 1960 brochure as having "Breast of Chicken Hawaiian and Crabmeat Remick"is still Creole and the interiors are still glitzy.
Now, for the bad news: The Pontchartrain has discontinued its nightly hotel rates in favor of elderly housing and extended-stay guests. There'll be no more tourist guests, but at least the famous "Caribbean Room" hasn't lost its name and accessibility, even if diners are leaving their evening wear at home.
