Just back from 5 days in NOLA. Mostly a "business" trip (looking for a place, moving down in July), but we tried a couple of new (to us) places in the Marigny, on Frenchmen, and had great meals.
Adolpho's. A little place (12-15 tables) on Frenchman serving Italian creole. Excellent rack of lamb ($20.95), mussels, escargot, pasta. For 3 people: 2 appetizers, 3 entrees, 2 bottles of wine, $130.
Santa Fe. Frenchman and Dauphine. Southwest with creole touches. I had shrimp and crawfish fajitas, which were excellent. Salsa was from a jar, but everything else was great. Dinner for 4 with cocktails: $110.
