Found this restaurant through reviews on here, though they were a little mixed there was enough positive for for me to give it a try.
The restaurant is on the main square outside the cathedral so full marks for location.
The site said it was open all day, which it is, but the buffet actually starts at 7pm so we had a short wait which we spent with a beer on the terrace people watching.
The buffet itself was quite extensive, salad bar, meat and paella section and a bar for Italian pastas etc, plus a section for deserts.
And of course it was an all you can eat for a fixed price, which for us was €13.90 each. This doesnt include drinks.
The salads were nice, crispy lettuce and the like.
We moved onto the Paella which won’t please anyone in search of authentic Spanish fare but was tasty enough, then we had ribs in a barbecue sauce, again, nice if not fabulous.
We added a few extras such as croquets and the like which again were ok.
Like most buffet meals you end up feeling very full very quickly and wondering if actually you had eaten enough to cover the price, but I would say that you do.
I would return here to eat next time, and suggest that if you are hungry, not looking for haute cuisine you should give it a try too
