My work is taking me to Lexington for a long weekend in a few days. I've been there several times before, but I feel mostly clueless as to ethnic food availability. I really like Banana Leaf near UK, but I'd like to know if there are other Asian or other ethnic places that are worth going to. I don't care about ambiance, location (as long as it's within 20ish minutes of the UK area), or price; anything authentic, whether hole-in-the-wall or expensive sushi, would be fantastic. Help me exceed my low expectations!
