Beaten by Cudzo, I was going to suggest answer d) please see the blackboard by the fire: ploughmans, simple sandwiches, soup of the day, jacket pottato with simple toppings, pint of pawns, fish and cips, sheepherds pie, burger, steak and ale pie etc. e.g. simple comfort food and fuel for the touring cyclist. Sundays it may include the roast of the day.
answer d) would still qualify as a pub as you sit in the bar and no you haven't got to book a table in advance.
