Went to Kabuto last night after it had been closed for ~2weeks for "renovation." When making our reservation, we were told Gen-san was taking some time off. Last night we discovered he is gone for good. The samurai behind the counter has even disappeared! I must say I felt very sad during the dinner. I really liked Gen-san, even if the rice was at times too warm and the fish progression always without rhyme or reason.
His number 2 (whose name escapes at the moment) was in charge with the general manager of the restaurant group (Monta, Goyemon, sushi mon) overseeing, literally, the entire bar peering over the chefs' shoulders. Fish was good, not great, but the cutting and saucing were widely variable. Some cuts, specifically bluefin group, were noticeably different sizes. Also, the chef saucing the nigiri was very heavy-handed - to the point of drowning out snappers, etc. A plus, the rice temp was consistently ok. It will be interesting to see how Kabuto holds up without Gen-san's quality control and dedication.
In all honesty, I'm not that excited to return any time soon. I will miss Gen-san and wish him luck. If anyone has further info, please share.
