Rather than agonize over the myriad options on the colorful pictorial sushi menu, try closing your eyes and pointing. The odds are good you’ll like what you get. The rolls are creative and beautifully constructed to balance warm and cool, creamy and crisp, savory and sweet. But there’s more to Koi than fish. The broad-based menu of Thai curries, Vietnamese pho and cooked Asian-inspired specialties makes the eatery a convenient middle ground for dining groups with varying levels of seafood-friendliness and raw-readiness.
