I recommend Flying Fish, but I haven't read much about it lately, so maybe it is not so great anymore. The new menu was great, and got a lot of praise. I just looked up their drinks for you, and these 3 sounded good to me. I have tried the chocolate martini at 2 other places, and really recommend it. Drink water or soda or whatever with your meal (out of pocket), and get your dessert boxed to go, then get the chocolate martini as your drink, but it really is a dessert. These 3 sound good.
