So, I'm in the foodservice business and one time I had to do some nutrition analysis on Welse Rarebit. Now, knowing what I did about British cuisine I figured it was some sort of offal. Then I discovered it's really just cheese sauce on toast. Wow. Sounds good. Then I discovered Big Ben and they serve Welsh Rarebit (as well as bubbles and squeak which I remember from Wind in the Willows or something).
They also make a mean Shepherd's pie.
I'm sure the fish and chips is good and it's probably their signature dish, but when I go there I always get a Shepherd's Pie, Beef and Mushroom pie, or some other awesomeness. Big Ben's is my favorite British pub in Charlotte and if I'm not feeling British I can hop across the street to Tyber Creek and get my Irish on.
