Why are dates "greyed" out?

[bizzybee3]

I was searching for available dining options on May 11th for DL & DCA, but when I click on the calendar to select the 11th, it is "greyed" out and I cannot select it (along with May 9, 10 and 12). This is the only week that is showing this anomaly. Is there something going on that week that would cause dining reservations to not be available?

You must be looking at the Blue Bayou?? It is closed for those days

I was looking at Carthay Circle Restaurant but that would explain it! Very bummed because I wanted the biscuits and duck wings, but thank you Robin2588 for solving this mystery!
