I went to Tamari for dinner on a Wednesday night. Had heard some pretty positive reviews so I was looking forward to this space.
It's a narrow, long restaurant without the feel of being too crowded. The decor is modern. It's not the most intimate space though. The kitchen is located just along the bar as you walk through to the seats in the back. The wait staff is very friendly. (There is a coat check).
The tapas were excellent. We had the seared scallops, chipotle tuna tartare, empanadas, and duck quesadilla. Our server explained each item as it was brought out, which was a nice touch. The sauces that accompanied each tapa were a great complement to the food and it all seemed to work together well. We followed that with a course of sushi (cali & eel/avocado rolls), which was good but perhaps not quite as good as the tapas themselves.
Overall, I would definitely recommend Tamari for good food in a casual and modern setting.
