It's pronounced Spanish-pirate-style: arrr-ah-GOAN-ah. The name comes from the medieval kingdom of Aragon; the restaurant is from Jason Stratton of Spinasse and Artusi fame. Chef de cuisine Carrie Mashaney was on Top Chef; running the bar is liquor-magician David Nelson, formerly of Tavern Law, Spur, and Il Bistro (the Sleepwalking Ballard, with cava, chartreuse, and limoncello, is inspired by a Lorca poem). The decor is tasteful and contemporary without feeling too corporate; the food is the exciting thing, and rightfully so—traditional Spanish dishes are beautifully prepared and improved upon in excellent ways.
