If someone asked you for eating/drinking advice in Arlington and you weren’t paying attention, you could pretty confidently answer “Lyon Hall” anyway. The main level here is a great group Happy Hour spot, with a handful of high-top tables and $5 beer and wine. Upstairs, there’s a quieter dining room that’s better suited for a date. The German menu has solid options whether you’re looking for a few small plates or a full meal. We can vouch for a pot of their mussels, their giant Bavarian pretzels, and the sausage platter.
