Service staff was very rude and even condescending. I will not return to an old chicago resteraunt or affiliat. While I have attended the same resteraunt on several occasions this is the first time I have been treated this way. The first time I have ever letf less than a 20% tip and the last time I will ever frequent their establishment do to the poor treatment and poor service. The bartenders were sub par, providing poor service and even having the audacity of cutting me off on a Friday when they had served me far mor on a workday earlier that week.
