contrary to what i believed this time last week, there are more than zero reasons to go to yonkers:

1. you get to ride the choo choo, and within a half hour of leaving grand central station, you can be in a cute little riverside town with bridges and a main street and a... 
2. seafood restaurant that is also a secret korean restaurant (!!!!)*. if you go there and disregard the seafood menu and smile and ask the owner for korean food, she will make you amazing korean food with black garlic and homemade kimchi. and she may even pour you a little cup of mushroom tea. everything about it is delicious and sweet.
3. line c3 might be there at a really awesome studio playing percussion music until the wee hours of the morning. and it is fine because you are fueled on thin mints and hot cross buns and yes, that korean food.

*ok, after further research, it doesn't look that secret, so here it is.

so if you're looking for a quick and easy little adventure out of the city {and your private jet is in the shop...} yonkers, i'd say, is a fun option!
