In reply to ceri:
we had food at the saracens head, it was pretty reasonable. We had just returned from 3 days walking with full pack at were mingin but the staff didn't seem bothered. I've no idea about their policy in dogs.
I wouldn't bother with the Cwellyn, last time we went it was expensive, mediocre and despite pre-ordering food with plenty of warning they were generally really pissed off with us having brought a group of 14 to their pub, despite the fact that we were well behaved and probably bankrolled them for the month.
