I was a couple times at the black diamond and every time I was there, the service was fantastic. but if the black hair barter works, the service is terrible. Wait 20 minutes for a drink, if it is not even busy, throw my food on the table, sitting on the bar on their phone, while the other barkeeper does all work. his pathetic, they should not treat their customers like that. I'm not coming back while she works there. I am also sorry for the other bartenders who have to deal with their laziness.
