Well there's that Qatar Bowling centre which is good, There is also City centre which has a small bowling alley at the bottom floor next to the ice rink (but i don't think that's the best place to bowl) and there's the place in Villagio at the back (Gondolinia) which is great! I'd recommend going to Villagio as it's right next to the food court, in a theme park and in a shopping mall.
