my sushi crazy uncle is coming here for a visit in a few weeks. he wants a nice sushi dinner somewhere in the core. i usually stick with toshi sushi, but would like to try something different this time. the ones that seem to get good reviews are omi, nami, japango and kaji. i would like to try kaji, but may be too out of the way. price is not really too much of an object, but i am mainly looking for a place that has great fresh sushi, good sake selection, and a room for conversation (that is why i ruled out blowfish) any suggestions?
