Della's is a breakfast/ brunch place located between the lobby of the Delano Hotel and the casino area of Mandalay Bay. I've visited Della's several times when in Vegas since it opened at the end of 2014 including a few weeks ago and I've never been disappointed. It's a somewhat higher end place and prices aren't the cheapest. Thankfully I've always had a food comp to use. If you're staying in Delano or Mandalay Bay, it's probably the best breakfast option in my opinion and worth a visit. That said, I'm not sure that it's worth travelling to if you're not staying in the Delano, Mandalay Bay, or maybe the Luxor. If not, there are better places on the strip for breakfast.
