I recently took part in a local exposition (ItLUG Latina 2012) and wanted to bring some MOC for the very large City Diorama.
So I decide to enlarge my old Street Cafe. At first I wanted to make it into a modular, but I didn't have enough time (and bricks), so I simply made it a little larger, with a more detailed interior.
To make it more realistic, I added a second entrance that takes to the apartment above and stairs to connect the floors:
At the cafe in the ground floor my minifigs can have a drink or have breakfast with coffee and croissant:
Above the cafe there is an apartment. The first floor is a dining room with corner kitchen. The second floor is a bedroom with a little space for computer.
Note: the big station behind is not a MOC of mine, but is part of the large City Diorama!
