Things might have changed now, but IIRC, the Mine Saloon had only Miller and Yuengling on tap and they had no food

Be warned, unless someone has been there more recently and things have changed.
Gettysburg is bit of funny as far as bars and bar food goes. There is a place that even calls itself "
The Pub", but they got tablecloths linen napkins and $30-40 entrees...
Battlefield Brew Works is an interesting place in several respects. It is located at a Confederate Hospital (Monfort's Farm). It is a local microbrew, which is hit and miss, but they are trying and are better than Miller and Bud. The food is akin to what you would get outside a Home Depot on a summer Saturday; at about 10 times the price. And they do have entertainment in the weekends, including local singers, open mike comedians and burlesque. And close at 11 PM. Interesting place, as I said.
O'Rorke's is kinda your 'standard neighborhood bar', other than the facts that they try to pass themselves as Irish pub, call themselves a 'family eatery' and have about 80 items in their menu. Blah in many degrees, but blah is better than nasty. Again, Bud, Yuengling, and the Irish Bud products (Guiness & Harp) only on tap.
Blue and Gray Bar and Grill. Nothing much about Bar here, and the Grill part is just out of a Greek Diner. With eggrolls too. Biggest attraction: their burgers named after either Union or Confederate Generals and come with toothpick Union or Confederate flags. Unless the Confederate flag ones are banned these days. Almost forgot. They come in 2 sizes: Little Round Top and Big Round Top. What would you expect with a name like that?
You would want to go to
The Garryowen Irish Pub. Decent selection on beer and Ales on tap, including real Irish as well as local microbrews, seasonally changing menu and some standard Irish pub fare. And not any 1863 pretense. The owners are Irish immigrants, and they know what they are doing. Probably the best bar at Gettysburg.
Gettysburg Eddie's. See O'Rorke's up there, substitute "Irish" with "Baseball" and you got it.
That's pretty much my Pub/Bar review of Gettysburg
