Positives - the chairs are comfy, the staff polite, the drinks are ok. Basic but ok. It was nice to get away from the crowds. A small but lovely bowl of fruit on offer.
Cons - food abysmal. A few grotty looking sandwiches - nothing hot. A few cold fried bits that should be eaten hot. Packets of plain crisps, dry crackers - no cheese or butter in sight.
Not worth the money if you have to pay for it. We only went in as we are BA silver members.
