おでん oden is my favorite midnight snack in tokyo. u can get it anywhere from any convenient stores ( aka the 24/7 deli ) which are everywhere. it is a traditional japanese winter dish of a bowl of light soy-flavoured dashi broth with boiled eggs, daikon radish, konnyaku, & processed fish cakes ... and it could be as cheap as 100 yen but the warm feeling that calms your tummy from enjoying a bowl of oden, priceless!
