Subway

Woah...Never would see this choice in the USA. Unfortunately there are no 500yen 30cm subs.
Yes, there is a Mushroom and Meatball sub. Yes, you do get real honshimeiji mushrooms with your sub.
Can I have a 15cm shrimp and avocado on honey oat please? Don't forget the mayo.

I don't know what Cheese-Roasted Chicken is but it sounds a bit like Chicken-Fried Steak and just as scary.

Also the Herb Dog is questionable
