Has anyone been to either Yamanochaya (山の茶屋) or Obana (尾花) in Tokyo -- preferably both for comparison?

I'm just putting the finishing touches on our itinerary and I'm trying to decide between these two 'Old Tokyo' institutions. Decision will be based on the unaju course as we aren't big on shirayaki or grilled innards. We've narrowed it down to these two restaurants based on feedback, ratings, and mostly their time-warp historic settings. I'd love to get some more feedback to determine which would be the better choice for lunch.

Thanks!
