Best I could do is Grash's in Milwaukee.
Fresh Florida Stone Crab Claws, never frozen, $22.99/#.
I would term them Large with a few Jumbos.
I purchased 8 claws for the two of us, some dry pack Bay Scallops and some Blue Points, yesterday.
If you do go to Grasch's, ask for 'Captain John' at the seafood counter.
He is the manager, orders only fresh, never frozen items for the main display case and is the most knowledgable person I have encountered in the Midwest retail market for seafood.
An interesting sidelight is that Grasch's has a Sushi/Sashimi maker working in the store producing some very nice take home sushi!
If you do go, check out the whole store, products ranged yesterday to some beautiful Prime Rack of Lamb at $49.99/# to Creme Fraiche from Vermont Creamery.
Bring your AMEX card! Prices are not for the faint of heart.-Richard
