The retro and mid-century modern decor will always be very cozy, whatever colors and decade you prefer. These can be neutrals with some copper shades, these can be bold colours like yellow or pink, these can be pastels. Go for mid-century modern furniture, leather chairs, various floor lamps, try reclaimed wood and reclaimed furniture.
Also, check out Blockhouse Coffee & Kitchen website. Interior or food, both are very good.
