Several different seafood restaurants operate under the name "Aw Shucks".

One of the most notable is Aw Shucks Oyster Bar on Lower Greenville Avenue in Dallas, Texas.
I don't know if they now have an official web site, but you can read about them here.

One with a VERY cool web site is Aw Shucks in Aurora, Ontario.

Yet another (with a similar name) is A.W. Shucks in Charleston, S.C.
There's also a location in Carmel, California.
