Las Gatas recommendations?

We went to Arnoldo's a couple of years ago and I'm afraid that we won't be back. Although the service was excellent and the location perfect as a starting off point for snorkelling, the food arrived cold and the servings were skimpy. When you're charging a premium price for food at Las Gatas, I would have expected more. To top it off, a large dog, owned by a beach restaurant owner, walked up to our neighbour's beach bag with a towel draped over it, and marked his territory. I'd rather spend my food and drink money at Barra or Playa Larga.
