I have been. The food and drinks are good... but it has a huge arcade which is expensive. I personally do not see the fun in an arcade anymore.. i've outgrown it.
Something i will say about D&B is that i know a woman who married one of the Vice Presidents and he is VERY VERY nice. From what i understand, working for this particular person is a delight. I am not sure whether it is that way in the whole company or just under his division, but i do appreciate companies that take care of their employees
