DFW Equivalent of Houston's Chase Tower Sky Lobby View?

I am planning to propose to my girlfriend within the coming months and am looking to do it with a breathtaking view. While Reunion tower was on my list, I feel like the steel cage structure around it sort of ruins the view. Are there any skyscrapers in the DFW area with a view and atmosphere comparable to The Chase tower's sky lobby in Houston (unfortunately now closed to the public). Thanks!
