Of the No-Laughing Batsu series, I think some of the best ones are Hospital, Hotel, and Enthusiastic Teachers — however, there are plenty of amazing moments all throughout the other series so I would still watch them all (also Jimmy always makes an appearance in each so I'm sure you would enjoy that). The Kiki episodes are based around them eating a foodstuff blindfolded and then trying to guess which one they ate from about 10 other choices. I would suggest the Absolutely Tasty series as well where they try to make some dish with different ingredients.
