My friend and I visited Japango for Lunch around 2pm and was able to order off the lunch special (it ends at 2:30pm).
I got the sashimi bento and my friend got the chirashi special. I would say the chirashi special is a better deal (you get way more sashimi, and the sides for the bento wasn't amazing).
We also ordered some 4 nigiri dishes (if you are willing to splurge, I would recommend the otoro nigiri (pink belly tuna). The tuna literally melts in your mouth. ($18 for 2 pieces). We also got the uni and it was really fresh and did not taste fishy at all. The horse mackerel was decent, nothing special. The hamachi wasn't bad either. Their sashimi overall is really fresh!
One thing that did annoy a bit was that the servers were rushing to take our plates away (and it looked like they were going for their lunch break and wanted us to pay and get out). I had some food and my plate and they decided to take it away without asking if I was finished :(!
Overall, the food was good and service was quick. I would definitely go back for the otoro and uni.
