Often the breadbasket was put out to keep diners occupied while food is prepared. That results in some underwhelming contents. Some diners would ignore the baskets because they were told that weight loss meant giving up all bread, so the bread would be wasted. At the very least, servers should ask if diners actually want bread with their meal.
One restaurant I recall from when we lived in Lubbock had a marvelous selection of three different kinds of bread in their basket, and I would certainly have paid for it.
I was able to read the article because my weekly email from Smitten Kitchen had the article unlocked. I was startled by the prices. I am not sure that I would pay $20 for a basket of bread. I would be thinking, "I can bake great bread for less!" I also noted that many of the breads trended to be enriched, so the butter content is likely higher than my current way of eating allows.
I would be more likely to splurge on a special dessert that I would not be making at home.
