Thanks, everyone, for your suggestions. I had no idea about Cheeky Monkey and Shish offering slices of cake, had never heard of the Highland Bakery or 50s Grill (it might be a bit of a drive for just a slice of cake, but I'm willing to try it!), should have thought of Key's. Lots of great places to try!
I'm looking for a place with seating (bakery, coffee shop, etc.) that offers good chocolate cake by the slice. I'm aware of Cafe Latte, of course, but what else is there in St. Paul? To get very specific, I'm interested in any of the following neighborhoods: Summit-University, Midway, Mac-Groveland, Merriam Park, Summit Hill, Crocus Hill, Highland Park, West Seventh, maybe Como or St. Anthony Park. NOT downtown or on the west side.
And are there ANY such bakeries in the northern 'burbs? Roseville, Arden Hills, New Brighton, Mounds View, Fridley, Columbia Heights, Spring Lake Park... Actually, NE Minneapolis would be okay, too.
I enjoy Cafe Latte, but I wanted to see if there are other options for cake by the slice in the areas I most often frequent.
