It might not be everyday you go to a diner and I am sure it is even more rare for you to eat their desserts. At Chelsea Square Restaurant they have a Seven Layer Chocolate Mousse Cake.  Sure you may have seen this tower of a cake at other diners, but seriously folks if it is served cold it is quite good. It is seven light layers of creamy chocolate mousse, looks whipped really. The chocolate is layered between seven very thin layers of moist vanilla cake. Covering this tower is a generous layer of chocolate, more of a fudge consistency. Go ahead and don't be shy. Step into this diner and get a slice of their Seven Layer Cake. Bring it home or eat it in the window as people pass by; they'll become jealous they too are not enjoying your cake.
