Thanks to all of you for your suggestions. I went with JIMINNM's suggestion of Enchanted Cookies and Cake. Verdict: Best chocolate cake ever!
I got the 10" chocolate cake with raspberry filling and chocolate ganache frosting. It cost $45. In hindsight, I should have gotten a much smaller cake because it is so rich and creamy that we still have 3/4 left.
Guess I'll just have to take cake with me to work every day for the next week. Oh, the suffering.
