I visited on a Monday night. Trying to decide between two different red wines, my waiter brought tasting glasses to allow me to taste before choosing. Very nice! But the service after that was inconsistent, with my waiter not showing up to check on my needs to order the next plate - luckily other staff pitched in. The plates are wonderful, very well presented. The artichoke, serrano ham and cabrales cheese with mixed greens (Tarta de Alcachofas) was fabuous, drizzled with balsamic vinegar. However my grilled beef tenderloin was a bit charred on the outside, somewhat overwhelming the cracked peppers and sherry sauce. The Delicia de Tres Gustos terrine of white, bitter sweet and caramel mousse was not as flavorful as I would have expected.
Overall, I would go back to explore the menu more.
