All our friends had raved about the food & ambiance, so my wife & I finally decided to try Louisianne's.  The decor is indeed cozy- like a nicely made-up cellar.  There was plenty of room at the bar so we sat there before our reservation time arrived.  Only two beers on tap, but both good local brews from Capital. \nEventually sat at our table & perused the menu.  Found many appetizers that sounded really good (including one of the specials that night) so we decided on sharing 2 apps and one entree... seemed like a good way to try a few items without getting too much food.\nApp #1 (the special): gnocchi in a savory cream sauce with crawfish was very tasty.  Seemed a bit light in the gnocchi (I think there were 5 or 6) but made up for it in sauce.  Two thumbs way up.\nApp #2: mussels in cream sauce... I had asked about the size of the mussels ahead of time and was told they were medium to large.  They were in fact medium to small, which was a bit of a bummer because we probably would have gone with a different app had we known.  But the flavors were good & we enjoyed sopping up the sauce with the bread.  And the bread they serve is quite good.  Two thumbs up.\nEntree: Crawfish Etouffe... I was excited to try this as I hadn't had etouffe in years.  It wasn't bad, but it wasn't great either.  If you went to a friend's house for dinner and they served this you'd be psyched, but at an upscale Cajun restaurant for $20 you may be left underwhelmed.  Two thumbs halfway up.  The salad that came with was fresh mesclun greens, with a bleu cheese dressing that was chunky but bland.\nMidway thru our meal the jazz combo started up and sounded really good- definitely added to the atmosphere.  For dessert we shared a slice of key lime pie... nice-tasting but no great shakes.  It seemed to be thickened with gelatin and I suppose I prefer mine to be creamier, plus it was lacking in zing, but only mildly.  Again, if your friend served it you'd rightfully congratulate them but for $6.50 it should be REALLY good.\nOur server was very nice & professional.  Absolutely no complaints there.\nThe nicest surprise came with the bill- only $70... and that included 5 drinks.\nWe have concluded that the next time we go we'll sit in the bar area and have drinks & apps.
