Perhaps we should start with the loo, not that I want to put you off your food, but it deserves a mention, being so state-of-the-art I had terrible trouble getting my children back downstairs to eat their food.

Yo! Sushi already boasts a conveyor belt on which its dishes rotate, parading provocatively past your table for you to pluck what you fancy. Oxford is also the only Yo Sushi in the country to build a monorail, complete with robot to deliver any food you order off the menu to your table.

But the piece de resistance; the prince of the porcelain, king of the khazi, duchess of the dunny and crème de la crème of the crapper, has to be the Japanese toilets which wash, buff and dry one’s posterior before you can say water closet.

Right up there in terms of the novelty factor, Yo! Sushi also provides the perfect opportunity to introduce a whole host of new food in a fun and novel manner. And with prices based from £2-£8.50 per plate, it’s not the end of the world if they don’t like the tuna maki sushi (they didn’t) because it only costs £2.80, but loved the gyoza dumplings (three plates later I had to seize back control), tried tempura’d sea bass and found a new penchant for popcorn prawns, Teryaki beef and Japanese puddings.

For those of you who have never been, you should try it. I know the concept seems bewildering, (friends recently admitted they had never tried Yo! Sushi because they didn’t understand how it worked and were worried about looking stupid) but it’s a brilliant and simple concept.

Arrive, take a seat at the circular bar or one of the booths. You get given a menu and water is on tap on the table. Then you have to play snap, by matching the pictures with the plates circulating around you, or just take a chance when you see something you like. There is also a bell on the table which you press to order something specific on the men, which may well arrive on the new monorail, beeping when it reaches your table. At the end of the meal the waitress counts up the plates, all colour coded to depict their pricing, and charges you accordingly.

It’s like having your face pressed up against a chef’s window, except that you can try everything you fancy without being restricted to just a few courses, which does go to your head. I had to forcibly prevent my daughter’s pulling dishes off the conveyor belt with the glazed look of Mowgli having encountered Kaa in The Jungle Book.

As for the food itself, it had its highs and lows, the sushi wasn’t great; the seaweed rings too stretchy and tough to eat, the salmon waxy and tasteless, but the Yakisoba noodles in a tangy sauce and crunchy fresh vegetables were great, the gyoza dumplings came in hoisin duck, chicken and vegetable varieties with a soy dipping sauce and were served piping hot, crunchy and soft inside.

Okinomiyaki – an authentic Japanese cabbage filled savoury pancake, topped with mayo, katsu sauce, spring onions and smoked bonito was strange but pleasing, the beef and garlic teriyaki beautifully cooked and flavoured, the popcorn shrimp (tempura prawns drizzled with a sweet shiro miso & chilli sauce scattered with chives) a massive hit with everyone and the crispy chicken wings disappeared instantly.

The ramen noodle salad coated in sesame sauce and garnished with pickled ginger, wakame and crispy shallots was a bit glutinous, the kaiso seaweed (marinated and served with edamame and carrots in a su-miso dressing) fresh and novel, and the ramen dumplings, basically a soup comprising of vegetable dumplings and crunchy vegetables in a miso broth with chilli sesame paste and ramen noodles was a course all on its own and terribly filling.

Pudding was even more bizarre, the wonderful chocolate moshi tasting like cocoa-dusted jelly balls filled with chocolate mousse, the Japanese souffle cheesecake or the custard dorayaki – a classic Japanese pancake sandwich with a light custard filling, all washed down with a strange soda that tasted of bubble gum.

With a new touchscreen plate window arriving soon, this really is a look into the future. So jump on board and enjoy the ride – if you can ever leave the toilet.
