There doesn't appear to be a thread dedicated to Hopscotch for some reason. I went there last night for the first time, and enjoyed it immensely, as did my dining companions. Very quickly:
1. Grilled chrysanthemum with poached jidori egg, bamboo shoot, and squid ink. A clever combination of flavors and textures that works very well, and which probably won't offend Alice Waters devotees.
2. Ginger braised duck gnocchi with brown butter creme fraiche, green onions. Very good indeed; I was quite pleased with it.
My companions had the duck fat chips (it is what it is; not bad at all if that's your thing), the pork chop (very nice, standard apple-y pork chop deal), and the day boat scallops (very nice, she said). We all had a "Yonsei Oyster," which is sea urchin, salmon roe, and citrus soy (also very nice, reminded me of the above-average items at Bar Crudo). Everyone was pleased. Cocktails were excellent, desserts were very nice (I had some sort of strawberry tart concoction with kernel corn and kernel corn ice cream, which was delicious.)
The server was very helpful and friendly, and I also requested as little salt on the food as possible, which they were able to accommodate.
Anyway, I would happily go there again. Below, a couple of photos. One is the gnocchi, the other is the chrysanthemum.
