Really solid breakfast spot :) The food was tasty and the service good at Della's Kitchen. I ordered an omelet with spinach, mushrooms, and tomatoes, and it came with hashed browns and toast. I wasn't able to eat it all - portions were pretty big. I enjoyed my food though! Aside from the omelet, I ordered their Granola as well. I still think about the Granola to this day! Nice-sized portion, so I wasn't able to finish that either even though I really liked it.
While I was very satisfied with my meal, I don't know if I would recommend people to go out of their way to eat here. The ambiance is just ok - the only view was of convention-goers walking down the long walkway to and from Delano to Mandalay Bay. And while the food was good, most of the items are dishes you can find at other restaurants. Dellas's is, however, a place I would definitely recommend if you are staying at Delano and Mandalay Bay.
