Lively French brasserie with standout mussels, excellent happy hour, and strong brunch; solid service and atmosphere, with occasional inconsistencies and loudness at peak times.
Lyon Hall delivers reliable brasserie dining with strong food quality anchored by excellent mussels, oysters, and French onion soup, supported by solid service attentiveness and knowledgeable staff. However, inconsistent execution on steaks and occasional seasoning missteps during busy service prevent a higher grade, while the tight seating when full limits ambiance appeal. A worthwhile neighborhood destination for happy hour and brunch, though not among Arlington's premier dining establishments.
One caveat: Noise can be high at peak dinner and happy hour; choose off-peak for quieter experience
