If you are asking for boiled, I'm gonna put my vote in for Hanks. Hanks Crawfish
I have tried a good number of places in Houston both small and large and hanks is the closest I've had to what I can get in LA.
They just taste damned good. I usually get the mediums because I love alot of flavor without alot a heat. But they still have a good "spicy" kick to them going down. Try Hanks, and I don't think you'll be dissappointed.
