I agree with the outlet comments but I suggest that you also check the plans and see if it is indeed a place of assembly. Look for Use Group A on the plans somewhere. Just because it can/will accommodate 100+ people does not automatically put it in Article 518. The type of construction and the design professional will make that call. If it's not a Place of Assembly you might be able to save a considerable amount of money using NM cable. As always, check the plans.
