I'm not quite sure what you are looking for, but it sounds like you want an all-you-can-eat buffet, but with a nicer atmosphere? Or a place that serves large portions like Don Pepe, but not as expensive?
All you can eat is too much food for there. Don Pepe is way too commercial for me. Most prices in that area are pretty reasonable. I am looking for a change from Spanish Tavern, Spain, Don Pepe. Decent atmosphere, good food, large portions! Thanks.
