Stepping into this pub-like restaurant, you might expect to get a burger and fries, or maybe a warming bowl of French onion soup.  You probably aren’t expecting to receive a history lesson to boot, but when you are seated at Booth Number Three, aka The Proposal Booth, and you’ll discover that you are following in the footsteps of one of America’s greatest leaders. Martin’s Tavern has been around for almost 80 years and has served every president from Truman to Bush (they're still waiting Obama to make an appearance). Each booth has a placard announcing what legendary leaders’ bottoms have sat in your seats -- from Nixon to LBJ to Kennedy. In fact, JFK proposed to Jackie in the aforementioned Booth Number Three upon their return from the Coronation of Queen Elizabeth. When you turn your attention from the booths to the menu, you’ll find comforting classics: burgers, hearty stews and chowders, shepherd’s pie -- even for late breakfasts and weekend brunches.  A hallmark of the menu is the Welsh Rarebit -- a cheddar sauce enriched with Yuengling lager and spices. You can grab a pot and enjoy it as an appetizer for dipping, or, you can order it with the Martin’s Delight entree, the restaurant’s version of a Hot Brown.   A hearty meal and a history lesson wrapped into one? More than many of us can say about a productive day at college, let alone a night out.
