It seems very unlikely that you'll get "PopChef.com".
"Sublettable.com" sounds like a real estate site.
The heat death of the universe will happen before you get Kettle.com, which is also a major US consumer brand.
popchef - makes me thing of popcorn. I prefer chefpop to pop chef.
popvenue - doesn't really bring restaurants to mind
sublettable = forgettable to me for some reason.
Of those you listed I like kettle.com or wanderingchef the best. If you're still open to new ideas, I'll toss a couple in the ring.
heretoday.com - This looks a little strange.
subtlechef.com - rolls off the tongue a little easier than subletchef.
Also, a little more description about your idea would be cool if you have time.

I would avoid the name 'popup' as it is associated with virus infections. Try cart instead.
