The lakeside patio is a great place to spend time people watching. There was no wait for a summer weekday lunch. Out of the dishes ordered at our table, the pizza was probably the most successful: nice thin crust with fresh basil on the margherita. I wouldn't say the food was very memorable but pretty decent and the location is what makes this restaurant worth going to.
Service was okay: not over attentive and not dismissive. I would definitely not recommend going if you are in a hurry but you might as well stay and enjoy the view anyway.
The draught beer menu is way too limited (only 4 available) but the food menu has good variety.
