Mark's is the best restaurant in town, but you'll need reservations.
Blue Water Bay, which is downtown and near Mark's, is surprisingly good. They have boiled crawfish - and it was quite good. I lived in Lafayette for 20 years and raised crawfish and have boiled my share - and my wife and I were impressed. Show these crackers how to suck the heads.
Harry's downtown is fun and has good fried crawfish and a good oyster po-boy, but mediocre redbeans and etoufee. New Orleans theme.
Mexico Lindo is excellent for Mexican food and is inexpensive - but it is about ten miles from campus.
All the traditional chains are here - mostly on Archer Road: chili's, bonefish, Fridays, carraba's, Olive Garden, etc.
I would stay away from places near campus (except for Mildred's) unless you are a student .
Sonny's is good, but Back Yard Bar B Que in Newberry is very good. But it is about 20 miles from campus.
