We have inexpensive arcades as well, which are a ton of fun. $5 gets you about an hour of entertainment, and I wouldn't go over 10 because you'll probably get bored of the games before you use up your credits if you put too much on it.

Some other options:

• go karts - a little expensive for the fancy ones, so shop around
• shooting range
• trading card game nights at the game shop

These all cost money, but probably not much more than drinking, and they're generally more enjoyable without alcohol. You can show up alone and have a great time, and there's just enough social interaction that you won't feel so alone.

But maybe this is my millenial side showing.
