We've got a sitter for a rare night out and are looking to try Korean bbq. We know nothing about it. Open to Chantilly, Centreville, or Fairfax area since it seems like there are so many options nearby. Less interested in quantity/value for money but moreso quality and overall experience since this would be our first time. Given this background, where do you recommend we go and what's a dish we shouldn't skip?
