       dispatch_queue_t dispatchQueue = dispatch_queue_create("q_getRestaurants", NULL);
       dispatch_async(dispatchQueue, ^{

           dispatch_async(dispatch_get_main_queue(), ^{
                [weakSelf doSomething];
           });
       });
    }



   -(void)doSomething{
       //can i use self inside this method????

Yes. You're good there. Only variables inside the block itself are retained.
