Ashley let us know about Mix-Drinks.mobi yesterday and I finally had a chance to check it out. The site simply offers you quite a few ideas for mixed drinks. The site is not that complex but it does have categories for the drinks so you can select the type of drink you are aiming for. There is no way to specify what ingredients you have so you will probably have to find the drinks you want before you head out to the store. There is a useful search function if you are looking for a specific drink. I searched for Malibu Bay Breeze and it came up as the first result.
