On offices... I like to think of them less like traditional office blocks (though in some conservatives parts of the system you might find them) and more like those ultra-swish "modern villages" you see cropping up in first world cities - building incorporating apartments, offices and other amenities such as eateries etc. It fits in with the idea of corporations replacing traditional cultural icons such as nations or ethnicities. The hypercorps are extremely wealthy and can be quite extravagant with it, meaning some gerontocrat might indulge in the inefficient nostalgia of creating your typical office building from the 21st century down to the gurgling of the water coolers. More progressive, tech-savvy hypercapitalists would have physical presences to their business only as much is logistically necessary - you need to have somewhere to ship and receive things etc. On everything else in habitats - this is largely left up to the GM running things in that particular hab. What do you think will take hold in this hab and who goes there? You'll find transportation infrastructure, physical markets, body banks and backup servers of course but you'll find things catering to almost every taste imaginable - including the criminal ones. On crop growing, people in the Inner System who want to make their own stuff CAN'T nanofab it because access to nanofabrication technology is restricted by the hypercorps (who want to maintain a traditional capitalist economy). Thus if you want food you don't have to buy from a store, you must grow it. On food, I always like to imagine nanofabbed food as being quite bland but nutritiously solid - think of a slab of tofu or other generic protein-stuff and that it is then subsequently cooked to provide flavor. This is a dynamic I worked into a Scum Swarm I wrote where one ship was made up of cooking afficionados who often held Iron Chef challenges to make the tastiest food out of the blandest ingredients that could be nanofabbed. I think restaurants would largely take two forms in Eclipse Phase - first, budget places that cater to people who just need to eat something and secondly places like the teppanyaki restaurants of today, where the meal and the show are kind of one and the same.
