Sushi - we like Sushi House in Wheaton (there's also one in downtown Naperville) or Sakura on Ogden Ave in Iroqois shopping center. For Vietnamese you'll have to go further north into Wheaton and Carol Stream. Luong Loi on Main St just north of the RR tracks in Wheaton. Nha Y is on St Charles Rd - go east on St. Charles Rd from Schmale Rd and it is on the right. Nha Y is better in my opinion with an extensive menu. Luong Loi is part chinese/ part vietnamese so some of the items suffer like the cha gio egg rolls which contain cabbage - blah. Luong Loi does have excellent pho though.
