Just a little feedback.

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.
