Here are some pictures from my Sunday Roast Lunch. I enjoyed the food, service and great view of the restaurant! I would recommend this George Grill & Bar; it is very spacious (two terraces, a bar, comfy armchairs with coffee tables), is located in the city center and offers a great variety of food and drinks! Here is the address:
