In the FWIW Mode, I've been looking for great espresso in NOLA since before Katrina, and have been pleased only twice.
Once was at a Community Coffee in the Quarter on a 3-group Cimbali . . . next time I came in, they had two commercial super autos. The second time was at the La Davina in the Quarter -- definitely not a La Marzocco -- but, again, it was only good the first time I went; the next two times, it sucked, and I gave up.
