Hearthstone is very zeitgeist-y. This is neither a compliment nor an insult, just a statement of fact.
Everything about its menu is designed to appeal to those who know just enough about food to want something better than Claim Jumper and Panera, but not so snooty, well-heeled and demanding that they are willing to spend $200+ dinner for the really good stuff. In this respect, it is very much like the newly opened Therapy: an amalgam of middle-brow, consumer-friendly signifiers (pizzas, small plates, pastas, burgers, etc. etc.), all designed and executed by good chefs, not a bunch of accountants.
