I'll start by saying that I love black dog and aside from maize it is my most frequently visited restaurant. I will not speak at length about the food. The meats and sauces are amazing. The sides are fine. Two underrated menu items that you must try are the rib tips (best value for your dollar) and the mustard sauce (although you can't go wrong with any sauce).
Now my beef :/ with the new location, service. At the Urbana location service was always top notch. The staff was friendly and knowledgable. At the new location, the friendliness is there but knowledge has been replaced with rushing you through your meal. I, like many previous reviewers, despise the iPad approach. It's awkward for ordering and especially awkward for tipping. The staff doesn't have the same knowledge/passion as before. We overhead a server saying that she couldn't recommend a beer (at a place that has a great beer selection) because she is more of a vodka girl. Maybe go work at Olive Garden? Yikes.
Another unrelated gripe. In the winter they have ceiling radiators that feel good when you walk in but if seated underneath may cause you to sweat through your meal.
Overall: great food, lackluster service.
