Early in the month I reported that the eat-all-day buffet pass you could purchase at the Orleans or the Gold Coast could be used interchangeably at both. I was given this information by a couple buffet personnel, but evidently this is not correct.
The prices are also not the same at both casinos. The all-day pass for the Gold Coast is $27 weekdays and $28 Fri-Sun. The prices at the Orleans are $3 higher, at $30/$31.
