I think it's a pretty good bar, still dig the no music/no TV thing (though a lot of people don't, and it's unpleasant to sit with friends who are impatient and whiny about the lack of music/TV). For my tastes, it's way more pleasant than the Biergarten and, while J. Ryan's is friendlier, more comfortable, and has a better selection, Clark's is a safer bet to converse with a group in a chill environment.
My gripes, aside from the ownership's odd comments and general behavior:
Staff isn't the most helpful or welcoming.
The sandwich, in my experience, is mediocre. I did not enjoy those dry hard rolls they switched to. If they're back to a decent onion roll from Harrison or someplace, it could be a whole different thing.
The space is too big. I don't see how anyone can generate enough revenue from this sort of concept to pay the rent on that many square feet. It's a beer bar with a limited menu and reasonable prices. I'm not in the business of finding solutions to those problems, but I think an owner would need some higher margin items (liquor) and a steadier stream of customers (full dinner service? live music? do they still have trivia?) to stay in business.
