Wow - fantastic! We were disappointed the first night when we walked in at 10:45 and were told they were out of ice and had just had last call. The second night a different bartender (Eddie) was very welcoming.
A friend and I enjoyed the Foreplay (shot for 2) - a decadent mix, the only thing I remember being Bailey's caramel cream, served in an edible chocolate cup. Arguably the best deal on the menu. When I couldn't find anything else I was eager to try, Eddie asked some questions and came up with a drink that included mango chile-infused vodka (hot, hot, hot!) and muddled strawberries and raspberries. I can't remember what else he added, but it was awesome.
Be warned, this small bar has only 6 seats, and even standing probably can't handle more than 8-10. It's awesome, cool and definitely a must if you're in the Palms Casino!
