You say bowling alley; we say sports bar, because that's what it is, damn it. Sure, there are 30 state-of-the-art bowling lanes in the main area, and the score-keeping system is so high-tech and obvious, there is no hiding a bad game, though the black lighting offers some degree of anonymity. But just look at the name of the place: "300 Dallas." That conjures up a bar, a nightclub, scenesters, maybe even a strip joint. There is a large bar, an attentive waitstaff that will help you with the size of your balls and shoes, good pub grub and flat-screen televisions playing mostly sporting events and placed in front of you above the pin decks, one screen for every two lanes in the bowling alley. Sorry, sports bar.
