Great food and service, although sort of odd ambiance.
I feel a bit guilty because I'd never even heard of the TV show and only really know of Gordon Ramsey as "one of the English celebrity chefs, a bit abrasive but also a solid chef". However, I saw great reviews of this place and I'm staying at Caesars so I got a reservation via OpenTable. It is still pretty full all the time, so I'd definitely recommend reservations -- a lot easier during the day than for dinner.
Seated immediately based on my reservation time. Menu explained by my waitress, and I ordered immediately -- the prix fixe lunch deal for $60, plus an extra signature appetizer (lobster risotto), espresso, and sparkling water. Total came out to $4.50 ($104.50 minus my annual $100 annual Caesars Total Rewards Diamond dinner voucher), and because I'm not an animal, I tipped based on the full amount (which surprised the waitress, which makes me fear for humanity). So, not an inexpensive place, but great food.
Lobster risotto ($24) was possibly my favorite dish. Perfect risotto, butternut squash, and maybe 4oz of perfectly prepared lobster on top. Apparently this is a signature dish which is always on the TV show -- I can see why, because it is technically challenging to prepare.
Pumpkin soup -- great soup, with some pepper oil and various "bits" in the bowl, with the soup poured over tableside.
Beef Wellington: surprisingly good. Also, I think this is $49 on the menu solo, or $60 in the prix fixe, so I would always order in the set. I'd only ever had badly executed Beef Wellington on cruise ships and event food; this was an entirely different dish.
Sticky toffee pudding with speculoos ice cream -- decent, but not my favorite style of dessert, with too much focus on sweetness and not much complexity. But, this does seem to be popular, and was good.
Overall, a good restaurant, although definitely on the pricier end, and hard to get a table, in a town full of great restaurants (including a bunch by Gordon Ramsay himself). The dining room is large and open and thus a bit loud, and while there is a somewhat open kitchen, it seems like they dialed back the "two competitive teams preparing custom menus" to "popular dishes from the show". I'd recommend trying the place if you have a chance.
