Hi, we are leading a group of ten, including my wife and I, and are very interested in an evening back alley Izakaya tour. I've read the reviews of the Sangenjaya experience led by Simon and it sounds exactly like what we are looks for. Realizing our group size is large, given the tour's description, is this either something that can be worked out or would we have to split into two groups? We would really like to keep together if possible.
