Yes, I've eaten at NY Stage before and know portion sizes are huge, but I still was amply shocked by what appeared before me. The amount of food on the plate is almost to the point of being unappetizing, so you have to order just one plate and share.
That being said, the matzoh ball soup would have been enough for the two of us, but we went ahead and ordered the whitefish "appetizer," which could have fed four people easy. The soup was kinda bland, but the matzohs were cooked perfectly. The whitefish was super yummy, if a bit bony, and served with bagel, cream cheese and the standard tomatoes and cucumbers. The chocolate egg cream was delish.
We felt guilty for not finishing the whitefish. I wonder how much food this restaurant wastes? It's not like Vegas tourists are asking to doggie-bag the left overs.
