if else condition inside for loop using angular

I am working on a task where I am looping an array inside a tag & using target=”_blank” attribute but one of the array element should not want this target=”_blank” attribute so what to do?

<ul *ngIf="item.menu">
            <li *ngFor="let subMenu of item.menu">
              <a href="{{subMenu.link}}" target="_blank">{{'landing.menu.' + subMenu.name | translate}}</a>
            </li>
          </ul>
