Casa Tequila Tokyo Kabukicho is a small bar in Kabukicho, Shinjuku, Tokyo, serving Mexican food and tacos. It focuses on tacos and nachos, grilling tortillas made in-house to order and cooking meat fresh. The shop is in a basement, so early in the day you can enter without a reservation, and orders are placed by QR code. QR order confirmations are slow, which leads to duplicate orders, and food and drinks also arrive late when it is busy.
