Totally depends on what you like to do. Tulsa has casinos like most everyone else these days. If you like museums the Philbrook and Gilcrease are both very good art museums. A half hour to the northwest is Woolaroc, a history museum of the west from pre-Colombian to modern times created by Frank Phillips. They have a lot of good local restaurants to explore. There's a nice zoo. I'm sure there are many more things I haven't thought of to entertain visitors other than basketball.
