Order by in SQL Server

I have data in table as below.My requirement is -->result should come in descending menu order i.e highest menu order should come first and if two records have same Menu order then the highest LastUpdatedDateTime   in those 2 records should come first

LastUpdatedDateTime         MenuOrder
2015-04-08 05:37:04.513       6
2015-04-08 05:37:10.783       1

Help me in writing the query for the same.

i tried like select LastUpdatedDateTime,MenuOrder from Table1 order by MenuOrder,LastUpdatedDateTime desc --->but in the result lowset LastUpdatedDateTime is coming first if Menuorder is duplicated
