Between its casual, no-frills setting and diverse menu, Isao is one of the most visited sushi restaurants in Thonglor, if not the whole city. Neighborhood regulars and hungry visitors come for its signature rolls, many of which boast well-balanced flavors that don’t detract from the freshness of the seafood. For example, Chicago Spicy Crazy with tuna, salmon, cucumber, avocado and spicy sauce has just the right amount of heat, while Caterpillar is perfect for lovers of unagi. The sushi sandwich, where fresh tuna and salmon is stuffed in between layers of ebiko-sprinkled sushi rice, also attracts a crowd.
