Gjusta is not a restaurant. When I was there, at 2:30 on a Monday in June, well after the lunch rush, every one of the few seats on the patio were occupied by campers who had finished their food and were on their laptops or phones, and nobody left in the 20 minutes we were standing up waiting for our food.
I have no idea why it took 20 minutes to slice some cold fish and put it on a plate. Maybe the fish station guy went on break and no one filled in. It wasn’t even good.
