I've driven past this place many times and want to check it out. Is this a restaurant that I can show up without a reservation, or is it only for events?

Should be good just walking in.

Me and my wife went there last week so do the elderly couple the place was closed down I don't know what's going on but it was not open

We usually just show up, no reservations unless a special event most times. Food is delicious, it's never busy when we've gone. Such an interesting place inside, they give tours during the "spend the day in Walton" and we've gone outside on top, what a view!
