Neat little place, with delicious, scratch-made food. Bartender/server was super friendly and attentive. Nice bar atmosphere - I think this would be an awesome live music venue. Not necessarily where I'd take a client for a business lunch, but just fine to go with a co-worker or a friend.
I had the Count and my friend had the turkey pesto sandwich. Both were excellent sandwiches. I had the pesto potato salad which was terrific as well. My friend had a ham and lentil soup that had more ham in it that most ham sandwiches.
All-in-all I think ThirdSpace is a nice place for a very casual bite to eat of a drink. When it's cooler, looks like a good place to sit and relax on the patio also.
