At Baisi Thai—whose fusion menu melds Japanese and southeast Asian fare—the staff takes presentation seriously. Sushi chefs decorate rolls such as the Rainbow Dragon, Green Turtle, and Caterpillar to look like their namesakes, with caviar eyes and vegetable horns. Bartenders fill cocktail glasses with neon-green Baistinis and other mixed drinks and, in the kitchen, curried noodles collide with stir-fried veggies and traditional Thai basil. The airy, spacious eatery, located at the Oakbrook Center mall, is striped with translucent space dividers, and avenues of thin, vertical reeds sway between orange columns and UN delegates researching models for international flavor cooperation.
