I visited on a Friday and everyone was dressed in business attire because they had just gotten off of work or were there for a late lunch. It appeared most everyone was meeting someone. My wife and I were dressed in casual attire but they treated us like visiting royalty regardless of how we looked. My suggestion would be to wear what you like and be yourself. Regardless of how you dress you'll have a good time and a great meal! I highly recommend visiting this tavern.
Had felt underdressed at lunch before
Just go classy-casual (smart)
We went for lunch on a weekday and were dressed very casually. We didn't feel underdressed or out of place at all. I imagine for the dinner scene you would want to be a little more business casual however.
