My main recommendation for you when you dine at Olives is the Beef carpaccio - probably the best $20 plate --er, I mean MOUNTAIN-- of thinly sliced raw beef you will find. The balsamic and whatever the other sauce they drizzle over it makes it so flavorful and the beef is very high quality. Plus it comes with polenta and you can't go wrong with polenta. Ever.
You don't need to read anything else.
But in case you're curious, other noteworthy points-
-Great view of the Bellagio fountain show. I would've liked to sit outside to watch it but it was RAINING the day we went. Imagine that, rain in Vegas..
-Good service. Granted it was lunch time, so maybe they aren't as busy, but nonetheless our service was very nice and the food came out fairly quick.
-Ravioli was just OK, probably not worth $22.
-Check the specials of the day. There was a seafood pasta on that menu the day we came and it was yummy.
-The flat bread sandwiches are very large and they come with a huge serving of sweet potato fries!
Overall, this is a fancier establishment but if you want to save some $$, come for lunch. Get the beef carpaccio while you're at it and sit back, relax, watch the water show!
