Did you get the bit where you go and see Yumi at her place, I have discovered I have made a mistake around that which could be related to your problem. (there is now a fix for that on the dev log page)
After downloading the fix I'm still having the same issues, I'm about to delete the whole game and redownload it and start all over again to see if that fixes it. Should I download the regular episode 6 or the one with bug fix?
I removed the whole option about Yumi, you will now just go and see her (click on car). When you get back, see the CSI girls and you should just go back to the kitchen and a lounge icon will appear. I have just updated the original link.
