We have actually had lunch in the Brasserie, not the actual restaurant.
Service: Friendly, efficient.
Food: Good quality, simple but well made. Perfect cooking time, delicate flavouring. Not highly technical or original but properly handled. Prices are good.
Wine: Very nice and cheap wine list. It lacks definitely high-end wines for special occasions. But you can drink very good wines without paying 100€. Service is good, good glasses, good temperature.
Overall very good impression. It is absolutely among the top two of Jyväskylä, the other one, in my opinion better, being Pöllöwaari (but slightly more expensive). Do not miss!
