Presently, Mythos is open until about 3:30 during the week but if it is extremely slow, it can close half an hour earlier. On the weekends (sat and sun) then they are open later to about 5:30 or 6:00. Last sunday they had to close much earlier because there was NO business.
The hours will change November because of the holidays coming up. Since the hours can change from day to day it is always a good idea to call ahead to find out the closing time. Also, make a reservation so that you won't arrive at a closed restaurant.
Well, that is all the information that I know about.
