I thought Defune was an ok sushi-place, but not great in any way. The décor was very bright and felt quite unwelcoming. Downstairs is a bit better, but still a bit of a hospital feel to it. The personnel, however, were very accommodating and service was as good as can be expected. I even had my ignorant sushi-questions answered in a friendly manner. I finally now know for sure that you’re supposed to dip only the fish part, not the rice, in the soy sauce. Apparently it’s not a life-or-death issue though.
Speaking of the food, I truly enjoyed the teriyaki, actually one of the better ones I’ve had. The sushi and the other food we tried, e.g. tempura, were good, but not spectacular.
What surprised me the most with Defune was the bill. It is truly expensive, and not really worth it in my view. However, if you’re not fazed by the recession, if you live in Marylebone and if you feel like having some sushi, then sure, why not? That said, I have yet to try the other sushi-places around the area so I might be adjusting this shortly.
