They live in Sidewinder. Specifically, the part of Sidewinder that used to be Nevada. Due to the open hellvent in this city, Lila has an easy time securing ingredients and scenic locations for their television show. They do not have family here, but they do have friends who live in this city.
Their home is on the fifth floor of a high rise apartment building. It has a bedroom, living room, full bath, and large kitchen. It is decorated comfortably, with various trophies displayed prominently on bookshelves and picture frames. The kitchen is stocked to overflowing, though most of their cooking experiments are not done at home but in the field and in an industrial kitchen.
Their bedroom is full of boxes from the last time they moved that they still haven't finished unpacking. Some things still don't have a place in their home.
They get their money by hosting a television show and owning (and sometimes operating) a few scattered restaurants. Mostly they have managed to own restaurants by getting into sizable debt with banks on the force of their brand recognition and business plans. In the television show they showcase unusual ingredients--sometimes ordinary, sometimes monster parts and the like. Their restaurants are big on 'organic' and 'locally sourced' ingredients, although those words are doing some heavy lifting in the mega city.
What do they spend the money on? Nicer knives, fresher spices. New all black outfits for all occasions. Access to newer, weirder ingredients. They've thought about getting a pet but they're just too busy to pay enough attention to one.
