Ended up wearing a nice black button down as that my host was going casual and goes all the time. I don't think I saw a tie in the house. I did see someone in gym shorts and shower shoes. Plenty of flip flops too.
Had the prime rib it was good but enjoyed Houston's better...
They funnel in buses of tour groups all the time, most of those people are dressed casual.
I don't go to Houston's because they kicked me out for wearing a tshirt...AT LUNCH...so **** em.
