Dashi-maki tamago, a rolled Japanese-style omelette made with dashi stock, is a staple item in Japanese bento boxes and izakaya. These days, the egg dish is also available as a sandwich and some of the best dashi-maki tamago sandos in the country come from Watanabe. Originally from Osaka, the Tokyo branch is located inside the Marunouchi Building close to Tokyo Station.
The standard fried dashi-maki sandwich (¥880) is filled with a rolled omelette that’s coated in breadcrumbs and fried at high temperature, resulting in a crispy coating while the inside is kept soft and fluffy. You could also opt for the onion-miso pork sandwich (¥980) or the shiso-sauce pork sandwich (¥980). Can’t decide? Go for the sample set that includes all three types (¥950).
Note that the sandwiches are only available for takeaway.
