We did this last night and I am sooo happy we didn't cancel. Josh's review had me worried about the view but it was a non issue. We were seated at table 703 which is the third table as you enter the lower patio up against the railing.
We started with apps of Potato Soup for my daughter and my wife and I shared a Scotch Egg and the Cheese Board. All were delicious. I loved the accompaniments that are served with the cheeses.
My wife and I both ordered the Fish and Chips for our entree and our daughter the Cheesy Pasta. The fish was excellent and our waitress confirmed they are serving Cod inside R&C and Tilapia (which she said replaced another farmed Asian species, Pangasius) out at Yorkshire. Her explanation for using Tilapia at Yorkshire was a bit laughable. She said they sell so many orders of F&C at Yorkshire that if they used Cod it would become extinct. I loved her and thought her service was impeccable so I didn't have the heart to call her on it. Whoever is feeding her that line though needs to rethink that explanation.

The only item ordered that was a bit underwhelming was my daughter's Cheesy Pasta. It was basically a large bowl of Elbow Mac covered in a very bland Bechamel Sauce. I'm thinking whoever put that together in the kitchen either forgot the cheese or they need to rephrase the description from Cheesy to Creamy.
The Dessert Trio was good but I was pretty filled up up on Black and Tans at that point to enjoy much of it. It was beautifully presented and what I did sample was well prepared.
I ended up having 4 pints and my wife 4 of the Specialty Cocktail. My daughter had 2 cups of Soda with each having a lighted clip. She got Buzz Lightyear and Ariel. Like others mentioned previously the drinks were free flowing and we turned down offers for more.
This was my first time eating at R&C and my first time watching Illuminations from that vantage point. My previous experiences were all in the FP area. This vantage changed the entire show for me. Maybe it was partly do to the 4 pints but the show had an entire new level of entertainment and enjoyment for me.
Again I encourage anyone who is on the fence about this to keep or get that reservation. I'm so happy we didn't get scared off and cancel this from our plans.
