Saw a recommendation in the archives here for LAN, decided to give it a try last night. Went with a friend and she didn't like it as much as I did, but she still thought it was OK. It is slightly pricey but not bad for a 'nice' dinner, $100 for 2 people, including 4 drinks & 2 deserts.
I had the ceviche of the day, which was good, but it wasn't citrusy enough. It was raw and there were several different textures of fish, which is nice. I also had a couple of pieces of salmon sushi, and my friend had the chirashi. I thought my slamon, and the tuna and mackarel that I had off of her plate were excellent, and she thought they were just OK. Turns out she likes her fish cold and firm and I like mine warm and mushy. This was definitely room temperature and very nice and soft.
We shared two deserts, the green tea tiramisu and the creme brulee. Both were fusiony and very interesting. The creme brulee had an almost tapioca-like flavor, which I loved, and the green tea tiramisu was dusted with tart green tea powder and served with a scoop of green tea ice cream. If you go (and you like green tea), you have to try this desert.
I would totally go again, and I definitely recommend this place to anyone who likes melt-in-your-mouth fish.
