Our group of friends usually heads to Tempe Mktplace due to it being a 'central' location for all of us that are at all extremes of the valley.... we've done D&B several times now and, though it's been enjoyable (it's always fun with good friends) with drinks and games, I find that it is a waste of $ and their food isn't even worth going in for dinner.
We've dropped lots of cash on the D&B cards.. we've drank and played... (I usually know where to play for the high ticket jackpots)... earned some tickets.. then, at the end of the night when we have combined all our tickets (apparently not really all that much), we find ourselves looking sadly at the *crap* they have in their little store and deciding we should just give away the tickets to any kiddos nearby and walk out while we still are in an up-beat mood.
Food is lame (better options nearby), service is standard, atmosphere is fun and so are the games.. but be prepared to spend a pretty penny for the game entertainment.
