Had a chance to stop in and have lunch at Banana Island today. They are, as far as I know, OKC's first and only Malaysian restaurant. They do offer a lot of Chinese style dishes as well if you aren't ready for the spicy, sour, and sweet flavors combined in the Malay dishes. My wife, who has had almost every tofu dish in most of the Asian restaurants in town, says theirs is the best she's had yet. If you are looking for something different, give them a try.
