My husband and I moved to Tybee a year ago and eat out a lot. We love the NBG for its yummy food and VERY friendly service. Right on the beach on the northern end of the island by the lighthouse, it is super casual without sacrificing the quality of the food.
We had dinner there recently. Started with drinks and an amazing crab dip served with 2 kinds of chips. My entree was the calamari-topped Caesar salad and my husband ordered the special, a hangar steak with broccolini and red beans and rice. Both were wonderful.
There is usually live music on the weekends which helps make this a perfect beach restaurant. Try it. We'll certainly be back!
