We often do one appetizer and then one entree to split between two people. Some of the entrees weren't really big enough to fully feed two average sized appetites, while others are. Some of our favorite combinations are the fried dill pickles (or potato soup) and meatloaf at Carnation, gumbo and crescent city salad at Cafe Orleans, and the French Market chicken (half a chicken) and beignets. The Monte Cristo (I haven't had it in a long while, but the last time I had it, it was easily big enough for two), Plaza Inn fried chicken, and ribs (6 ribs plus two sides) at the RBT are big enough for the two of us in my family with average sized appetites.
Regarding WCT, the lasagna was big enough to share, but the other entrees I've tried (Osso Buco, Alla Vongole, and Braised Beef Ravioli) were sized for one average sized appetite.
