Dining rooms are often one of the most luxuriously decorated rooms in your home. These examples are no exception. One interesting trend I've noticed is a dining room that actually looks like it was converted from a living room or parlor like the one shown here. Since it's a room more likely to be used, it may be a good use of the space, provided the traffic flow works well from the kitchen.
