I thought the BOK Center was fine. I actually liked the venue and once we found the better food vendors, all was good.
But downtown Tulsa was a major disappointment. The people I met downtown were very nice, so it pains me to say this, but the downtown area was depressing - with very few locals to be seen, closed shops, few bars and restaurants. Maybe its been that way for a while or maybe covid shutdowns hit them really hard - I don't know. We eventually found some better places to eat/drink on the outskirts of the city, but that's not the same as having a lively area downtown. I've been to 6 tournaments now, and Tulsa is the only venue to which I will not return.
