We have eaten at Key W Cools a couple of times.
I find it an interesting place to eat. We have had mixed experiences there. Mostly good, but did have one trip where we ordered a pork chop that turned up a little dry (but DH had a great steak). Probably should have sent the pork back, but didn't. Prices were on the higher end of moderate (so not a cheap meal) but not excessive either.
I would go back there (Key W Cools) again, however if you want great steak - try Charlies Steakhouse - we all had an awesome experience there. Prices are higher than Key W Cools, but well worth it.
If you have a coupon, try it out. I would guess $25 would get you a fair portion of an entree - so sounds like it would be worth it to me...
