Concert wear works for me. It wants to be high-end/upscale, reality, height nor price without the flavor makes them neither high-end nor upscale, just pricey. Mid/Upper ok in my book. Service was very good. Reservation, suggested, if you want a widow seat.
You can dress nicely or you can hang out on the lounge side in more casual wear. Yoga pants would not be appropriate :-)
