They do have a fair price, but it is hit or miss on the quality. And just so you understand, the crawfish they cook on the porch are top quality.....but, you can't buy those live. You get a 30-35# sack from the pile. I've had great and the worst from there.
But, if you aren't particular, go for it. Otherwise go to Zydeclaws where you are buying from the same stock they cook. Make a reservation.
