Best Chocolate Cake, Gregg's Restaurant in Providence. (worth the drive)
When I have a craving for a chocolate cake I drive down to Providence to a restaurant called Gregg's. They also have a bakery section. The cakes are reasonably priced.
They have the best chocolate cakes and lemon cakes I have ever had. Their eclairs are huge and awesome, also.
They are located at 1303 North Main Street, Providence, RI.
