RE: Lee's Hamburgers
I haven't been to the Lee's in Metarie, but I have been to the one on Veteran's Boulevard in New Orleans.
They have great onion rings. It is the same recipe that Popeyes uses (and I think that they are the best in the world!)
I really don't remember the hamburger that I had all that well. I eat at Bud's Broiler sometimes, though.
