What should I wear to your fine establishment.

One Man's Opinion: Business Casual at minimum.

Here's a tip for any fine dining spot: dress well, and you'll get a better table and better service. Restaurants put their VIPs in the best sections, and VIPs do not like to be seated next to guests wearing football jerseys and flip-flops. If you look around an upscale establishment, you'll see people dressed in shorts at tables near the toilets. If you're dressed like a CEO, they'll seat you near CEOs.

Not jeans, but anything from business casual and up. I've even seen someone in a tux once.

This is an upscale restaurant that caters to a wide variety of clientele. We noticed every dress from casual to formal, but mostly business casual. Service was consistently high level with all classes of dress.

I often were khakis and a jacket or nice sweater

Also there no longer free valet parking. It was $8 or $10 last time i went there. I

I would say business casual

Jeans are fine. Overall, diners wear upscale casual, but there's no dress code and servers won't get snooty if you show up in jeans and sneakers.
