I see you're in Tunkhannock, so I'll give you a rundown of where people end up hanging out. Mind you these are bars, so if she's not really into drinking.. well maybe Tunkhannock is not a good choice to meet people her age
Downtown Tunkhannock:
The Beagle - This is a spot that has a lot of "regulars." Around holidays it gets PACKED with people coming home from college or visiting their family. It's pretty much a dive bar, they don't put any money back into it. That said, the drinks are cheap and the people are pretty nice. I have seen a few fights break out there, but overall I'd say it's not a bad place to kill a night in town. There are 3 billiards tables (bad condition), 4 or 5 dart boards and a horrible shuffleboard table.
The Second Wind - Avoid this place. It's worse than the Beagle by FAR. The people that hang out here... well, unless your daughter is a biker who is into the trashier side of white, I'd steer clear.
The Prince Hotel - Mostly for older people. My wife's grandmother goes there on occasion. I heard that the owners of Twigs recently bought it, though, so it may get better.
Bogeys (Shadowbrook) - This isn't really "downtown", but it is a nice bar just on the outside of town (rt 6 E heading towards Clarks Summit/Scranton). They have 4 older large TVs behind the bar, a jukebox that occasionally lets out a country tune, and a nice mix of ages. Generally, the earlier you go, the more golfers/older gentlemen you get. As the night goes on, the age gets lower. They have really good boneless wings, too.
Around Tunkhannock -
McGrath's (Dalton) - This is a nicer bar, but a lot of Tunkhannockites venture there. Mostly Mill City/Lake Winola because of the proximity. They have bands play relatively often and 2 billiards tables (good condition). A lot of people that go here also go to the Beagle (or used to), so you get a sort of crossover crowd. There are also a lot of Lackawanna Trail and some Abington folks. I'd recommend this one, as it's the cleanest and the people are a little less .. rural.. than the Beagle.
Wellington's (Clarks Summit) - Nice bar with good food. 4 TVs around the bar for your sporting events. I usually go to this bar with my dad/brother after Xmas shopping. There are some people from T-Town that head down to Wellington's on occasion, and some general T-Town -> Abington transplants. 1 billiards table in decent condition (the felt is FAST) and a bunch of sit-down seats for folks who want to grab a bite. They also have live music pretty frequently.
Blue Pelican (Lake Winola) - This one's more of a hidden place, and unless you live around Lake Winola or have friends there, you probably haven't gone. To be fair, I haven't been to this place in well over a year now, so it may be different by now, but here is what I remember: Very blue lighting. They have a "tropical" type theme, and a small stage for bands to play, although I've only ever seen two people play there. They have a billiards table in the back in a room that is much too small for a billiards table (horrible angles to hit the ball), so if she's really into billiards, I would NOT recommend going there.
Creekside (Tunkhannock) - This one is a bigger dive than the Beagle, but I've heard good things about the food there. The people that go there are usually locals (East Lemon or near Deer Park Lumber).
Lake Carey Inn (Lake Carey.. obviously) - This place is hit or miss. It keeps changing management. When it hits, it really hits. Large place with 2 bars, really. A back room for billiards and bands (nice) and the front bar for chatting / sports (2 larger TVs and a projection). There are seats for the hungry with a view of the lake. Definitely a nicer bar for the T-Town area. Lots of locals unless it is open mic, then a bunch of Beaglites head up.
Minuteman (Lake Carey) - this one is on a side road leading to Lake Carey, but it has really good food. The bar itself is another local spot.. not really a huge hangout.
The Bog (Adams Ave, Scranton) - A "hipster" type place, so if she's into that, she should go here. Lots of college-aged kids and a recent smoking ban (recent being the last few years..). Decent bar, but really dark last I remember. The jukebox sucks.
Hops n Barleys (Luzerne) - AWESOME food. I go here to eat whenever I am in the WB area. I've never actually sat at the bar, but they have TVs and a good jukebox. The eating area is separated from the bar by a wall, so if you want to chat, it's all good. Definitely recommend at least going to eat here.
I can't think of anymore at the moment. I guess it depends where she wants to hang out. Tunkhannock has more "rural" types than the cities, obviously. You'd have to ask someone else for the bars in Scranton/WB.
