Fun place and great happy hour. There were four of us and we ordered a variety of dishes, mainly to introduce one of us to Greek food. Ok, so maybe the food isn't "authentic," but Petra is certainly a good place to hang out and check out all the beautiful people. :) Skewers were good, hummus was good, the Greek salad featured very large chunks of cucumber, sliders and pizza (nope, not Greek to me!) were good but not outstanding. Service was attentive and friendly and the decor was modern and tasteful, highlighting warm brown/gold tones.
If you go for happy hour on Thursdays, you can also check out the farmer's market (open until 8pm)!
