I took my family there to celebrate my oldest son's college graduation last year. It's a great experience. The food is snooty and good. Of course it's expensive. But, it's a special occasion restaurant and that's expected. I say go. You're going for the experience and the view and you'll make a great memory.
They suggest reservations but not required, you might request a seat by the window for better viewing. Dress decent, something you would wear to church, or business casual etc. Most would consider the food decent but a little pricey ($50-75 per dinner with a drink or two).
Wife and I went this past Saturday for our 28th Wedding Anniversary. Food was decent, service was very good. view was fantastic. $170.00 for three drinks, appetizer, dinner, a dessert and tip. She had the chicken, I had the lamp chops.
Special Occasion place. Did see Bob Barry JR. come in just as we were leaving.
We had reservations and had requested a window seat.
