Isomaru Suisan Shinjuku Sanchome is a seafood izakaya near Shinjuku Sanchome Station in Tokyo where diners grill clams and crab at their own table. It serves tuna hoe, fried egg, sarada, kaisendon, and eel, with a grill set at every table. The restaurant is open 24 hours, orders are placed by QR code or a multilingual tablet, and payment is made at the counter. Smoke from the grilled clams fills the interior, making it uncomfortable to sit and drink for long.
