We've eaten at Havana Koi twice now. The first time the food was excellent: interesting choices, and everything we tried was really good. We especially loved the mango and Asian pear salad: crisp, delicious, with clear flavors of mango and Asian pear. The second time was a strong disappointment: we shared 6 of the smaller dishes (a mix of salads, small plates, and sides); two were good, three were so-so, and the mango and Asian pear salad was dismal: a barely detectable trace of mango, a slimy dressing, and so much raw onion that we couldn't taste the Asian pear at all. We'll wait a while and try them again -- maybe this last time was the chef's night off.
