Arcade Games:

This Arcade has snacks and drinks (you can make anything Vegan here Strix!) but it's not really a meal. Mostly hummus and chips, soup, and pretzels. We can only go between noon and 5 because after 5 it's 21+ (boo for being the baby in the group, only 7 more months though!) If we do decide to go here, there's no cover charge and each game is either 1 or 2 quarters, depending on the game. We would definitely need to grab lunch before or dinner after (or both) so I guess keep that in mind when thinking about the total cost. Also since it's just arcade games, we could always do something else after we're done here (:
Ice Skating:

It's $10.50 for all day +$3.50 skate rental or $8.50 for a single visit +skate rental. I am horrible at ice skating though. But I guess I'll throw this in here for fun.
Bowling:

$5 per game, full menu, $3 shoe rental. There's also an arcade upstairs.
There may be more things to do, sometimes I find it better to just wander and stumble upon something.
