3 friends and I went for restaurant week. Iruna has great ambiance and charm. The service was top-notch, and our server made excellent wine recommendations. The desserts were amazing. The other food was just ok.
Here's what we had:
tapas - tortilla espanola (which was complimentary) was delicious; chistorra (chorizo in cider w/ baby artichokes) was also good; pan con tomate was surprising because it didn't seem to be tapas. rather it was huge chunks of grilled bread that didn't work well to distribute flavors and was oily.
entrees - trout with salsa navarra, eggplant, roasted peppers, onion and tomato was very nicely cooked and had a nice balance of flavors. filet mignon with tomatoes and salbitxada was order medium rare but delivered very well done and over-salted. It was refired, and v2 was the right temperature but still over-salted.
we glanced at the patio on the way out which looks fantastic. We return to try some other tapas and sangria on their outdoor couches.
