i've got no experience of shooting kitchens but maybe it's worth mentioning there are a few shiny/reflective things in kitchens (fridges, ovens, metal surfaces, marble tops)..so diffuse light could be useful as well as direct sunlight through the windows 'lifestyle' pictures. flash or some hardlight sources might create problems. i'd do some wide-angle but also get a few close-up 'macro'-(style) details to mix-things up graphically if the imagery is meant for brochures.
