Craving raw fish

Just realised I haven't eaten sushi since before I went on holidays, which was five weeks ago! Since I've worked back till after 7.30pm and don't feel like cooking or washing up, I'm off to rectify the situation. I've tried countless types of sushi, but my favourite remains tuna and avocado rolls covered in cod(?) roe. A lot of other people share this preference, so the plates tend to get grabbed off the conveyor belt pretty quickly. Hopefully, I can get a seat near the end where the new stuff's loaded on...
