Fortissimo's was at the corner of Louisiana and St. Charles. I passed there yesterday and there was a big
'Restaurant Liquidation' sale sign in the window. So I guess you can knock this one in the head.
I had several light lunches there - salads or sandwiches, and everything was pretty good, and it was such a nice space - but all I really remember is a friend of ours complaining that they once took 45 minutes to make his corned beef sandwich, and he was the only customer in the place.
