Let's face it: We're officially in the age of Astro Bowling, when teeny-boppers flood bowling alleys on Friday and Saturday nights and toss gutter balls amid techno music and black-lit lanes. But even on weekends, the Sea Bowl Entertainment Center in Pacifica is the best tenpin venue around, and it all but overlooks the ocean. Even if the recently renovated center is a little too brightly lit for old-timers' tastes, it's clean and efficient, and the lanes, equipment, and bar are all top-notch. Leagues pack the place on some nights, so you should call ahead to reserve a lane, but there are good group deals and plenty of other amusements if you forget the reservation and have to wait. In an area with a dearth of gritty, beer-scented bowling alleys, Sea Bowl is the best of the new breed.
