I like that Josh Barro stepped in (on?) the pseudo-controversy that arose when Joe and Jill Biden ordered the same meal by saying, yes, it’s fine to order the same dish as your spouse. I mean, of course it is, but that didn’t stop people from arguing otherwise.
Once he was on the topic, he had a number of other recommendations such as “Consider the restaurant’s specialty” and “Try to be ready to order by the time your server asks if you know what you want.” So much of it is common sense, but as we all know, so much common sense like this is ignored by people. Maybe even you. I recommend you go read that and adopt those recommendations.
Speaking of restaurants, this is a very interesting walk down memory lane or history, depending how old you are: The 40 Most (American) Important Restaurants of the Past 40 Years. Some of them are well known: Chez Panisse, Spago, The French Laundry. Others are more obscure. Regardless, it’s a great article. (I slipped in American, because it is only American restaurants.)
