When I go here, I generally tend to show up on week nights. It's got a good feel that's both relaxed and intimate. You can hold a conversation over surprisingly well-priced wine. It's obvious that this place is the owner's passion project (I've heard it's the same owner of Delux). He/She probably thought , "Panini's plus wine equals cool," and they were right.
What really works about this place is that the food is as good as the wine you can order. Added to that is the pricing of everything. You can stop by for a good late night bite and eat/drink stuff that you'd normally have to open a vein to pay for.
