For a casual night in Beech Grove, try O'Gara's Irish Pub (affectionately called Johnny O's). It's typically filled with lots of regulars, but they seem to be friendly enough and don't stare... too much! We like going to O'Gara's because it isn't too far from our house, so we could, theoretically, stumble home if needed.
O'Gara's has a decent beer selection, and as an Irish pub, they have Guinness on draft. They also have all the other drinks you would expect at a full bar... I usually go for the bloody mary because they give you nice big olives with it.
O'Gara's has enough to keep you entertained for a night in Beech Grove, with a pool table, darts, Golden Tee machine and other games. Â You can also bring your own deck of cards or borrow their's for a game of euchre, etc. They used to have a cornhole game set up, but it disappeared. :(
They serve food at O'Gara's, but I haven't ate it at a time that I was sober enough to make any judgments on it... However, a big bonus is that they actually let you order pizza from the next-door Ball Park Pizza and eat it in there(once their kitchen is closed). Go for the pizza! Â I do remember eating it, and know that it was really good.
