Oh...do you have an hour?
Well, I bowl at a Brunswick Zone center. That should say it all right there.
First thing I would do is demolish the entire "cosmic bowling/birthday party bowlers area", trench out an area 6 inches deep and make a real pit area where you are forced to step up on the approach like a normal center. All the house balls in the back, go back to tables and chairs on the carpet.
Next I'd replace the newer Brunswick synthetics with wood lanes.I may just only have the last 30 feet wood just to make it interesting but I'm tired of every house going up or going to synthetics instead of wood.
The biggest thing to change is the scoring monitors and system. I straight up sucks. Before was a Brunswick 2000 system which was terrific and simplistic. I'd get rid of the garbage Windows based system, actually have pit monitors like the old days and would replace every CRT monitor with 42" LCD tv's. Vizio, Sharp or Samsung.
This is just 3 expensive measures I would do. I could go on forever.
