Is there a spot for steamed blue crabs?
No need for that. If anyone has any, these people should. BUt you will have to call to see and check prices.
They are about a half mile from Bethesda metro. Bethesda has a circulator bus that goes around the downtown area which will take you right near the restaurant, except Sundays.
If you just want some casual or takeout place, no need to go anywhere, there is a wellknown fish market right at the wharf.
I don’t think the crabs from Bethesda warrant a visit.
