The Japanese Sando — a sandwich where the beef is breaded and flash-fried to give it a crispy exterior and soft interior — is quickly gaining popularity in the States. When it opens tomorrow, Wall Street-based Don Wagyu will be serving the most expensive version in America. The nearly $200 sandwich starts with a five-ounce cut of wagyu, sourced from a single farm and aged 36 months. It's then breaded with panko, fried, and placed on crustless squares of white bread. Joined on the menu by two more affordable options, it's served with nori-dusted fries and housemade pickles and is best washed down with one of Don's available whiskeys, sakes, or beers.
