So, seeing as I just finished writing down my characters' favorite foods for a Q & A, might as well list some of them.
He generally likes spicy foods, grilled meats (and meat in general), and black coffee. His absolute favorite food is medium rare steak frites with either chermoula or spicy steak sauce and the fries topped with red wine reduction, over-roasted mushrooms, and some cheese. (Partially based off of this really good steak frites I had at a restaurant my family and I go to for New Year's Eve.)

She really likes seafood (especially fish and chips), salt and vintage chips, and dairy product like milk and ice cream.
Ice cream, anything to do with ice cream, and more ice cream! Zanzibar chocolate and mint chocolate chip/peppermint bonbon being his favorites. He also likes whole grain waffles topped with cocoa nibs, honey, almonds, and other super foods. If only to save face.
He really likes breakfast foods like pancakes, french toast, and waffles. He also really likes peanut butter sandwiches (he had is own brand of peanut butter one time!), his girlfriend's pies, and that fruity cereal they only sell around halloween. (Once spent all the reward money he got one time buying out the city's entire stock!)
