I cannot speak for the customer service, as I received a small "chocolate chocolate chip" cake as a thank you present from a colleague.
It was super moist, chocolatey, not too sweet, and delicious. I really appreciated it! It wasn't the best I have ever had, and was rather "conservative" (traditional, classic without a twist), but it's definitely above what you'd get at, say, Boston Market or KFC for chocolate cake. Or laying out on a table in a plastic clamshell at the grocery store. I prefer my chocolate cake to be more fudge-y or ganache-laden, but their cake is still solid.
