R&C is great. I have strong Irish and English bloodlines, and feel "at home" in that entire pavilion, even though I've never actually been to the UK.
Anyway, I've only eaten the Cottage Pie, and loved it. Best variation I've had, but the others were mostly my own pathetic creations, and a few from some local Irish Pubs here in town that feel much more branded than authentic.
Service was fantastic, but I had to giggle (and fake naivety) when he explained the different beers in the Imperial Sampler to me as if they were completely absent in the States. I could have differentiated these common beers (that I drink all the time, sans Strongbow) from aroma alone. I just ordered them up because for the price, is the best beer-bang-for-the-buck at the WS.
