As one of the few Michelin rated restaurants in Vegas, it definitely has the pedigree to back up it's exorbitant menu prices.
There are various dining options, from small tasting menus, to large tasting menus, to a la carte. Either way, you cannot escape this place for less than $200 for two people, which is not terrible for a culinary institution such as Guy Savoy. You are also showered with treats from the kitchen throughout the night.
Make sure to ask to see the wine list, even if you are broke from gambling. It is worth flipping through the large Encyclopedia like book of wines just to see what a rich person might drink...and what you and I can only dream of one day tasting!!!
The decor is surprisingly minimal...which is great because the highlight of Guy savoy is not the restaurant itself but what comes out of the kitchen.
Make sure to make a reservation and live it up!!! It is well worth the money and time to experience a place such as Guy Savoy!!!
