Mar Vista Bowl, on Venice and Grandview, is the best of the bunch. It's the cleanest and most air conditioned. It has the best pinball: Medieval Madness and Star Wars. Even a pro shop if your that hard core. Discount prices on weekdays before five. You'll notice that almost every bowling alley in L.A. has a Pepe's. Don't eat there, the food is terrible. I've heard the food at the bowling alley in Burbank is good, but that's practically in the Valley. Oh my God!
Bay Shore Bowl on Pico near 4th St. is a little run down. The lanes almost always break down, especially with a 14 lb. or heavier ball. The arcade is lacking, but they do have air hockey which rocks almost as much as Medieval Madness.
