We were there nearly two weeks ago, and, apart from the fish and chips, I don't think the food is that authentic in terms of the combinations e.g. my DS had the Prime Rib steak which was served with Yorkshire pudding and a jacket potato but we would normally have Yorkshire pudding with roast beef, roast potatoes and a veg.
DH had the 'surf and turf' and found it different to the British version - he found the steak not as tasty but more tender.
I had the roast chicken - that was okay too but nothing more than that.
We found the servers and everyone there extremely helpful, friendly and anxious to please.
