When it comes to sushi, I'm a big believer in you get what you pay for. You're not going to find high quality sushi sets or bentos for *that* cheap, because it's sushi, that's just how it works. Except for Dozo. Dozo is the exception.
They do a special lunch set menu for £6.90, and it is literally such a good deal. You can get sushi and sashimi sets that will actually fill you up. There's chirashi, unagi dons, tempura, teriyaki and katsu bentos and ramen, and it is all delicious and all £6.90.
Seriously, I was in two minds about putting this in here, because I go here every week and I like that I'm always able to get a table because not that many people know about it. But I'm telling you anyway because I AM SUCH A GOOD PERSON.
