It is worth going along for the fun factor. The whole concept is very fun and enjoyable. The options to see pictures of the menu, the webcam, games and being able to change the ambiance of the table (we changed ours to match my outfit!) are all great and very funky!
Ordering was easy and there was no delay in receiving food (even on a really busy Friday night). Being able to check your bill as you go along is also a plus point, it also shows you the cost of what you have ordered as well as the overall total, which is handy if splitting the bill between friends. Service was ok, we were asked to wait in the bar for 10 minutes for our table and were given complientary nibbles while we waited. There was a nice fun buzz in the restaurant.
The downside is that the food is very average and slightly overpriced, there was nothing particularly bad about it, it just felt average and nothing stood out. As the prices are in between that of Wagamamma's and Nobu, I expected the food to match but I felt that the standard of food was the same as Wagamamma's but almost double the price.
It is still worth a visit for the novelty factor as it really is a very cool idea and I really enjoyed the evening on the whole, just don't expect to have mind blowing food. You'll come away talking about the excitement of the projectors rather than anything else.
