Depends on what it is but i hear some meal sets are fairly cheap/affordable in Japan (one friend i know said he got 300 yen (about 3 bucks) ramen from a restaurant before), versus something like sushi (if anything i hear going outta your way to eat 'junk food' and such which makes it harder to get fat compared to american takeout or so )While I envy her ability to eat all of that, I cannot help but be slightly terrified of how much she must spend on food.
