Just outside of the Rhumbar is a drink station where you can get a variety of drinks without having to go into the main part of the bar. This station was my place of choice to get drinks all weekend while I was recently on vacation in Las Vegas.
I have an unusual affinity for Pina Coladas, and that was my go to drink every time I visited the Rhumbar. I bought a 'Yardstick' on my first visit for about $17, and came back several times to get refills for $12. I would also add an extra shot to my drink each time, which was $2 for the cheap stuff.
My drinks were strong, yet tasty. When I stopped at a different drink spot to get a Pina Colada, it was not nearly as strong or as good as Rhumbar's. The woman that worked at Rhumbar was also very friendly each time that I came by.
If you are in the vicinity of the Mirage, and would like to get a quick drink to go, I highly recommend the drink station at the Rhumbar!
