Food is uh… college cafeteria food. Campus dining food is pretty hit or miss, but they always have soft serve, fries, and 5 pizza options so those are always good, even if their entrees aren’t great that day. You can check out the menus online, so you can see if they serve food you like! (Just google “oberlin cafebonappetit” and you should be able to find them) Co-op food is better tasting but there are less options. You’re pretty much stuck with whatever they cook that day, which can be limiting if you have any strict dietary restrictions (like allergies, vegan/vegetarian diets would definitely be the norm), although I’m sure they would be willing to work with you the best they could. Off campus food is pretty great though. Kim’s, Feve, Agave, and Slow Train/Local are delicious and reasonably priced for an off-campus treat every once in a while.
Honestly, I have no idea how competitive they are, but it seems like there are a bunch of them so you could probably get on at least one if you’re really interested. Most things at Oberlin are really inclusive and want everyone to be able to get involved in some way, so I would guess the improv community would be pretty similar.
