The free valet option is the best. Just get out of your car and walk in. Tip the attendant on your way out. I have found parking on my own but why when it's so easy?

No. It's casual to formal. As to large groups, I would call ahead. I'm sure they will be more than happy to help you.

No but recommended for large parties and holidays.

Four to six it's in their website

A Bar/restaurant called Sidekick's.

Creme Brule yes. Chocolate martinis I don't know

Nice place.
