Tony Roma's Chocolate Martini recipe

I was at a surprise birthday party and wow oh wow, this is the best drink I have ever had. The first one went down pretty quick. I like sweet stuff. By the time I got my second one half down I was feeling the first. Had to get a few glasses of water the second one. My third was in my left with my fifth glass of water in the right. Before I knew it it was down too. Terrific drink. A1
