Had lunch there recently and was a bit disappointed. It was a choice of only three dishes, each served with salad and beverage for 9.50 euros. I had a potato and vegetable dish which, although tasty, left me a bit unsatisifed. The portions were just barely adequate for the price, and the salad (though extremely tasty) covered half of the not-very-large plate. Since there were no appetizers or other salad options, I would have had to order a second lunch dish just to be full, not very economical. In short, don't plan on this being your largest meal of the day. Dinner may be another story, but the prices are of course much higher. For dessert I had a coconut panna cotta which was quite tasty.

Cons: small lunch portions, limited lunch menu
