Is this causal attire?

Casual to business casual

You don't need to break out the tuxedo but business casual to semi-formal attire is recommended.

As casual as it gets, this is the best upscale restaurant in the region. The only place in the area that cooks steaks perfectly. Be prepared for amazing table service by professional wait staff. Cheers!

Yes it is. Great food and great service...you won't be disappointed

Yes

I recommend dressing business casual and up. Ive seen people in jeans but they look quite out of place.
