The one we played the MLS All Stars in was class. Is it in Chicago or somewhere? Can't quite remember.
Hopefully one of our friends from across the pond can help me on that one.
We played a friendly in 2008 against the Chicago Fire at Toyota Park, which is 30 miles outside Chicago and I doubt what you're referring to. Solider Field is quite magnificient, right in downtown Chicago and on Lake Michigan, but Everton have never played there.
You may be referring to the match against the MLS All-Stars this past summer, which was outside of Salt Lake City I believe.
