El Buen Vino is the most conveniently located Argentinian in Valencia. Other than that, it is not particularly well known for anything horrible or spectacular. The menu is fairly short (as is normal with the Argentinian restaurants - you are meant to eat steak and steak) and diluted with a few Mexican and Portuguese dishes. Not too cheap, nor expensive, for an Argentinian restaurant. The interior is a fairly strict mix of modern and traditional. It feels a little too empty for an intimate meal, more suitable for a more formal thing, like a business lunch. They are probably aware of that, being located in a business district of Valencia and calling their menu del dia an "executive menu". It is one of those rare restaurants that also open for breakfast.
