Looking at reviews, although TA reviewers love it, there are a lot of bad recent reviews on Yelp, eg only 5 pieces of beef as standard in Shaking Beef, bad service, food mediocre at best, etc. I've never been to San Francisco before and will probably never have a chance to go again, so I don't want to waste one of my few meals on something overpriced and mediocre (as some reviewers suggest). I see it's a James Beard finalist which is reassuring. I'm going primarily for the Shaking Beef but also because it's meant to be so good.
Other places I plan to go are Gary Danko, Wayfarerer Tavern and probably Straw (and, I confess, In-N-Out as I don't expect to get back to the west coast).
