Hosting WCF in IIS 7.0 / Windows 2008

If found this to be helpful

1. Run an elevated command prompt
2. Run the following command:
   

   "%windir%\Microsoft.NET\Framework\v3.0\Windows Communication Foundation\ServiceModelReg.exe" -r -y

3. Last and also very important is the need for a base address, it seems IIS 7 does not figure this out by itself:

<system.serviceModel>
	<services>
		<service name="RESTService.Service" 
				 behaviorConfiguration="Default">
			<host>
				<baseAddresses>
					<add baseAddress="http://localhost:80/" />
				</baseAddresses>
			</host>
			<endpoint address="" 
					  behaviorConfiguration="Default" 
					  binding="webHttpBinding" 
					  contract="RESTService.Service" />
		</service>
	</services>
</system.serviceModel>

Just speficy the baseAddress and you should be good to go. Navigate to your svc file and you can start consuming it.
