You know, at the risk of heaping on the negativity, I read their Yelp ratings and while some are excellent, others are genuinely a sign of a restaurant in crisis. Consider the gentleman from New Zealand who made reservations via an email to the owner five weeks in advance, spent the afternoon walking around downtown LA to avoid rush hour traffic, and then showed up only to be told that they were closed for a wine tas…
Then you talk about an example where they forgot to cancel a reservation, and one where the restaurant was closed and a customer didn't call ahead to check before driving for an hour (why is driving for an hour through rush hour something that reflects on the restaurant?). Then one guy who didn't like the food style.
None of those point even remotely to a restaurant being in crisis, so let's look at your last piece of evidence - claims of poor service. Is the service poorly rated on average compared to other similar restaurants? How did you check? Based on how much more poor their service is compared to other similar restaurants, how did you determine that it is a sign of crisis rather than a weakness of the restaurant? (There are many places with good food, but weaker service, which we do not call 'in crisis')
