Its a Rs. 5000 service here in Islamabad at Honda Center Peshawar Road (they do give discount if you're a regular customer. They check previous bills and receipts...). They clean the spark plugs, air-filter cleaned, throttle body cleaning and adjustment, full engine bay dusted using an air gun, they hook the car up to a computer/scanner and check the car for any error codes and clear them if they can, battery terminals cleaning, they apply a product "Carb-Cleaner" to various engine parts. Its a 2 hour job if there aren't many cars there. I had the full engine servicing done on my '07 Civic Hybrid just 3000KMs ago and it makes a world of difference in performance, engine and throttle response sharpens up, fuel economy goes up etc....
