While I can't speak to earlier service when iHop first opened I can say that my experience was good. Our server, Ciara, was attentive and cheerful. Our food came fast and was tasty. I made sure to write into corporate and compliment their service, something I encourage people to do for chains. These folks always hear about how badly they're doing, seldom about how good.
I rate the food as a three star but the service as a four.
