2 words: SNACK CART
That's all you need to know!! Just kidding - there is more to Harvest than the snack cart, but that's basically what's most important.
I work nearby and decided to walk over to Bellagio on my lunch break. I was able to make a last minute reservation via Open Table, even though it was a busy Saturday night.
The layout of the restaurant hasn't changed much from when it was Sensei, which is fine. It's open, with a large kitchen in the center of the room (where you can see the action).
Everything was VERY good, but my suggestion is to order everything the snack carts have to offer - they are small plates and the selections change.
The service was excellent, even though our server accidentally charged someone else's check to our card and then had to reverse it and recharge us. It happens, and he handled it well.
This would be a great place for a special occasion - it's nice, but not too stuffy and it's a fun atmosphere.
