The best restaurants serving Spanish food in St. Martins Caerphilly South Wales

The wait staff were lovely, the food was delicious and the drinks were very tasty. One concern though, we ordered a starter, a table close by ordered the same, their's had extra bread. I passed it off as it wasn't a big deal. But then I ordered the penne spezzatino and so did the table next to me. Mine had tiny cubes of beef in it, the table next to us had a piece of steak, sliced on top of the pasta. I heard both tables order, no one asked for any changes or extras so couldn't figure out why the same dishes were different across the tables?
