Mussels Meuniere or steak frites in Hartford, CT area?
While this is not in Hartford it is worth the drive.
Restaurant L & E in Chester had mussels steamed in Belgium beer with frites on the menu in mid December, and they were delish! Their menu seems to change often so I would check before you went. They might even have steak frites on the menu.
We have eaten at the bar and in the main dining room, both are great, but we liked the bar best.
