I got a list in Sharepoint 2010 with a choice column. The choices are checkboxes.

How do I query the choice column using the rest api?

I've tried using

http://sp2010/_vti_bin/listdata.svc/mylist?$filter=myChoicesColumn/xxx eq something 

and then I get

No property 'xxx' exists in type 'System.Collections.Generic.IEnumerable`1[[Microsoft.SharePoint.Linq.DataServiceEntity, Microsoft.SharePoint.Linq, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c]]' at position 6.

What property should I use?
