The friendly staff at Del-Mar Lanes has supplied amateur bowlers and seasoned ball launchers with pin-poaching fun for more than 20 years. Once decked out in pairs of hardwood-hugging shoes, groups can descend upon one of Del-Mar's freshly slicked, new Brunswick pro Avalon lanes. Sideliners can meditate upon their next moves while levitating above Del-Mar’s newfangled Brunswick furniture, or quaff deeply from a bubbling pitcher of soda. Thumbs retreat from tight grips to pluck handfuls of warm popcorn or nab fried delicacies such as mozzarella sticks, curly fries, and chicken strips from a sampler platter of six appetizers. Mini bowlers and novice rollers can boost their games with lane bumpers, which frustrate the efforts of hep alley cats aiming to bowl existential zeros. At the snack bar, full-grown hunger helps itself to classic bun-bound savories and other treats to feed their muscles, and adults of any stature can purchase fermented ales (costs not included with today’s deal).
