I found on the menu page if the menu item description exceeds more than one line the dashed line and price no longer line up as they should.
I corrected it with my own css but haven't checked it on any mobile devices so I'm not sure if its a good fix or not. My fix seems to work on a 1080p and 1366 monitors in the latest Chrome, IE and FireFox.
Could you verify the problem on your end and get back to me?
Thanks
