There was time in my life that I was at Keegan's at least once or twice a week (don't judge me!) and here's the scoop on what you should order:
Sliders and a Stella. They have prime rib sliders, with a zesty horse radish Dijon mix that's outstanding.
Look at the menu board, but Thursday nights should be Yankee Pot Roast night.
Potato Skins. Big plate and good enough to share.
