I couldn't get a reservation at The Laundry Room, so we decided to go to Oak and Ivy instead. The bar is tucked away in a shopping center called Downtown Container Park. After entering the shopping center, head back and to the left. Oak and Ivy has a small bar inside and additional seating outside. The outside area wasn't open when we went, though that may have been due to the cold weather, late time and/or small crowd.
Our server was very friendly and knowledgeable. Given that they offer an extensive selection of mules, so we decided to try a couple. He then explained that they make their own ginger beer for use in their mules. We tried the Irish Buck Mule and the Kentucky Mule: both were delicious. Sadly these were some of the only good cocktails that we were able to get while in Vegas. I wish we could have tried a few more of their drink options, but the bar closes relatively early at 11 PM (on Thursdays).
