Dreadful service at the bar., we stood at the bar in full and plain view for 25 minutes waiting to be served and it took another customer who just got to the bar who was offered service by the bar staff to point out that we had been waiting longer. Very poor service from the bar staff. Not to mention the fact that she made a mistake with our change . Not very easy to manoeuvre once away from the bar area as I have mobility issues and struggle with stairs so need to use the handrails and security staff wouldn't move on the stairs to enable me to use the handrail even when I explained that . Don't think I will be back.
