Some time around 2007, possibly a few years before, I had my first Wagamama in the Oracle in Reading, and I had a dish called saien soba. This dish was removed from the menu some time between 2014-2020.
It was a large comforting bowl of noodles, tofu and vegetables in a broth. It was vegan if ordered with specific noodles, and I loved it at the time. I ate it a few more times after that, celebrating when Wagamama came to my home town of Bournemouth, but I eventually realised that it was the plainest thing on the menu.
I started eating other things instead - the yasai katsu curry, or the yasai itame (another noodle soup, with a spicy coconut broth), things with more flavour. I wonder if this was removed from the menu due to its lack of flavour - but then again, why did it stay on the menu for so long?
