Jeans and a sport coat suitable attire for the Chophouse?

I personally would not wear jeans. You have a more up scale crowd.

I have seen that worn there. I would recommend a button down with it.

Could you do it with a nice shirt? Yes, but dress pants take the same amount of effort and look classier.

Yes sport coat and nice shirt. Tie not required

Casual

Yes casual

Yes

Yes acceptable

I've seen people in there and ghetto wear so yes that should be fine
