I'm thinking of prix fixe menus or special seasonal deals.
I like Luke's daily set menu of three courses for about $20. I've had it twice and both times have been more than satisfied by the large portions, and everything has been delicious with the exception of a mediocre crawfish bisque. The $7 mason jar of rabbit and duck liver mousse pate is also a steal from the regular menu.
Also, Palace Cafe's Monday-Friday summer temperature lunch is an eye-opening bargain. Went today and had a very generous serving of a good, slightly spicy and full bodied tomato and basil soup to start, and two filets of paneed flounder over scallion, tomato, and spinach with lemon butter sauce. There is no choice of entree, so call ahead to check if it'll be something you like. For the starter you can choose turtle soup, soup du jour, or a Werlein salad. The price is the previous day's high temperature multiplied by 10, so today's was $8.80 for both courses. That's cheaper than a lot of poboys!
What other prix fixe bargains are out there?
