Neco is a great value for a no-thrills good meal. The Mediterranean buffet lets you eat all you can and it is open both in the day and at night, all week long. The interior is a simple cafe, although quite tasteful, so it's not quite a classy romantic dinner, but you have mountains of all traditional Spanish and Mediterranean food, as much as you want, from salads and paella to meat, fish and deserts. A real bargain in the expensive Valencian centre.
