I'm surprised that Cambridge doesn't have many sushi places. Surely they've always had plenty of Japanese students around, and plenty of posh metropolitan types? Or does it not work like that? Anyway, I have found two proper sushi restaurants in Cambridge (UK) so here's a quick review.
(Actually, as well as these two, in the middle of town there's a Yo Sushi and soon-to-be a Wasabi too. I've nothing against those chain shops but I don't think of them as proper sushi, simply because you can usually only get tuna and salmon stuff, they don't have a proper sushi selection. Good for convenient food but not the full deal.)
U-Sushi near the Grafton Centre is a friendly little place that does a lot of takeaway. The fish could have been fresher, but there's plenty of variety on the menu and I particularly liked their vegetarian california rolls, made with asparagus, avocado, cucumber, shitake mushroom and pickle.
Japas just off Lensfield Road has a bit more of a restauranty vibe, if that's what you're after. They also seem to do plenty of takeaway. The fish is the same quality as U-Sushi and the range is pretty similar too. I wouldn't bother with their deep-fried ice-cream for afters though, it's nowhere near as much fun as it should be.
Anyone got any more tips? Let me know. There must be a secret sushi palace secreted around here somewhere...
