Any Welsh People here?
If you're going to West Wales, I understand that Tenby is experiencing something of a food renaissance?
From personal recommendations, I would recommend both Cnapan and Llys Meddyg in Newport Pembrokeshire. (You can also stay at both establishments to avoid waddling out to the car afterwards?)
Avoid Aberystwyth at all costs.
We really like Jugs Restaurant in Llansantffraid. The recently re-did their dining room from rustic and warm to a sleek leather-clad affair, but the food was still good. Their aged Scotch beef is excellent, as is the pate starter. The owner is on the floor most nights, and he is very friendly and personable in an 'aging rock star' kind of way. We visit Jugs any time we are in Wales. http://www.jugsrestaurant.co.uk/
Hi, I don't know about Wales but there are lots of places just over the border. The Stagg Inn at Titley, Herefordshire has 1 Michelin star, which it prefers not to mention but, is a great pub with splendid food. Slightly further north in Shropshire you have the Ludlow Ghetto or foodie heaven depending on your viewpoint. With lots of superior restaurants and food suppliers. I should think that's sufficient to explore for a few weeks. Have fun!
