I can't really answer whether Charlie Trotter's is stuck in the 90s, but I can say that the food is absolutely delicious. If this represents fine dining was like in the 90s, I have to wonder why we didn't just stay there:

The middle three courses - the halibut, the rabbit, and the lamb, were as good as anything I've ever had; six months later, I can remember exactly what they tasted like. That was the lightest preparation of halibut I've ever had; it was light, flaky, almost like skate, but without losing that dense flavor that makes it halibut. The rabbit was my favorite course of the night, and maybe my favorite ever. Moreover, the pairing with the "Scyri" was absolutely brilliant - there was an incredibly intense earthiness to the wine which fit perfectly with the rabbit, mushrooms, and rye cracker. The wine was a lot like drinking mud - and I mean that in the best way imaginable. There was a kind of mustiness to it which seemed to make every flavor and texture in the rabbit dish pop in my mouth. The lamb would have been fine on its own, but pairing it with the pannisse is what set it over the top. The pannisse was rich & creamy almost to a consistency like foie gras; when eaten together with the fatty lamb, it was like an overdose of savory. Between the fat & "meatiness" of the lamb, plus the nuttiness of the chickpeas, and the olive 'funk', it felt like it hit all of the 'savory' receptors in my tongue simultaneously.
Admittedly, the first two courses were fine, but not especially memorable; I suppose that is consistent with the 'meh' reviews others have said. But the peaks were so high for me that I'd still rate it overall as a phenomenal experience. It brings to mind Howard Hawk's measuring stick for the movies - "Three great scenes, and no bad ones". Dinner started with two good courses, followed by three phenomenal ones at its peak, and then three "merely" good desserts to close (though I did especially enjoy a lychee gumdrop that came at the end). I grateful for the time I had there, and I'm sorry to see it go.
