We had dinner here on our first night in Olsztyn. The restaurant is situated right on a lake and very popular with the locals, and we had secured a reservation on the very morning of our visit. The food - a starter of octopus, fish mains of zander and halibut - were all fine, as was the very nice sourdough bread and the spiced butter. There were issues with the service however. We had ordered a bottle of white wine when we ordered the food. The starters came in no time at all, and the mains while we were still on the starters. We reminded staff of the wine - once, twice, until I went to the bar counter to remind staff that wine was to be served with the meal...The bottle finally arrived when we were well into our mains (i had almost finished mine). For what is billed as a fine dining institution in a 4 star hotel, this service issue should not arise.
