I am a fan of oysters, and the ones I had at Sammy's recently were
I enjoy the seafood at Parrain's, and it's plenty for one person, but definitely not as big as Dempseys. Seafood Platter (when I was growing up, at least) was something two adults could split.

Still.. their fried seafood tastes great IMO
