Last week I had a really good burger in West Virginia at:
Greenbrier Grille and Lodge :: River Place Restaurant and Lodging :: Marlinton, West Virginia :: Breakfast :: Lunch :: Dinner
Twas a good honest burger. Guy I was with (a food snob like myself) called it the "best burger he had ever eaten."
Is it the best? I dunno, but it was really good. If in WV, try one out. Just a basic really good burger at a fair price. No frills. No show. Just really tasty. How tasty? I'm still thinking about it a week later tasty.
