To answer my own question, we checked it out tonight. It was okay - nothing to send in the troops for, but fairly solid. The burgers were not a replacement for the dearly departed Cat Mountain, but they weren't bad. They're next door to a convenience store that stocks high end chocolate, gluten free goodies, sandwiches, kombucha tea, and the like.
Part of the appeal for us, I think, is the completely bizarre drive down Cuernavaca, where you can have a $500,000 home next door to a trailer park.
We went soon after it opened and enjoyed the spinach salad and the pulled pork tacos. burger was ok as you mentioned. I think they're still working out their menu as I noticed they added a few more entree type dishes. i hope they do well--it looks like they spent a lot of time and money putting that place together. the provisions side has some great specialty items (i'm obsessed with the spanish olive oil tortas) but they are pretty $$$....
