Make sure to tell waitperson. Sometimes they are not aware of others' time.
Hour and a half
You should be fine, be sure an let you waiter know you have tickets
We hung out in the lounge before dinner. We were there for a few hours. Dinner itself probably took about 1 to 1.5 ours maybe? I would think you'll be ok with a 5:30 reservation. Also we showed up early to have drinks in the lounge and checked in when we got there, we actually got called for our table before our reservation time because we checked in early. Hope this is helpful, enjoy dinner this place is amazing!
