A couple of years ago, my son Jimmy and I decided to start a new business venture together. After hours of research and lots of thought, we knew that we wanted to do something fun while serving others. The conclusion was easily reached to open a mobile bar serving fairs, festivals, weddings, corporate events, and all other special occasions.
Our goal is for every bride to be able to sit back and enjoy her day ❤ Let us do the work! Let us help to give you a night to remember!
And, don't judge us by our silly profile pic 🤣

Kelly and her son we absolutely amazing! We hit the jack pot when it came to hiring this company for our wedding! Kelly helped me every step of the way on what I needed to buy for ...
the amount of quest we had and also she answered all my question on recipes to make signature cocktails. Kelly messaged me the day before our wedding just to remind me that I didn’t need to worry about anything and let the day flow how it should. Her and her son arrived on time to set up the bar and everything looked great! Everybody at our reception complemented us on the bartenders. My husband and I sat and talked to them on and off through out the evening. At one point I even saw Kelly walking around and cleaning up the tables as the night ended and she didn’t need to do that! Amazing job. I can’t say enough good things, we will continue to use them for any and all of our bartending needs!!!! Thank you for making my day even more special and less stressful!
