Full all the time due to great food! Lots of variety on the menu. Good variety of drinks. Outdoor is near road so not ideal.

Had a nice dinner here. I sat on the patio in Summer with the shade and nice breeze. Nice atmosphere. Service was pretty good. Food was above average. It was higher priced but worth the extra money. I will definitely return if in town again.
