Party For An 8 Year Old

My son is turning 8 on June 16th. I haven`t the slightest idea of what to do for him. He likes Labron James so i thought of having a Basketball party for him at an indoor Gym. I want him to have one of the best parties an 8 year old could have. We have already gone to the Roseville Waterpark and he is too old to go play at Chuck E Cheese. If you have any suggestions on a venue please contact me. He is a really cool kid that doesn`t ask for much. Never complains. Thanks
