There are some dishes you experience whose taste lingers with you for days. The pecan-crusted salmon ($20.95) at Café Hidalgo is one of them. This thick fillet of salmon is bathed in a honey-dijon sauce that tastes almost caramelized, then it's topped with crushed pecans and served with mashed potatoes or rice and steamed vegetables. It melts in your mouth. And that sauce . . . It's amazing. The super-friendly waitstaff and beautiful Villa de Sol setting don't hurt, either.
