I had this awful craving for tantanmen around the end of the year (hazards of translating about them) and ended up buying a two-pack to make at home: Nissin's Queue-Worthy Restaurant-Style Tantanmen. I didn't want to get my hopes too high, but this was wonderful! Not just better than that sad restaurant but legitimately very good in its own right! I thought at first it was a matter of low expectations, but if anything, the second pack was even tastier.
The first photo is a standard tantanmen with ground meat and leafy greens, and the second is a meat-less (slash forgot-to-shop) version substituting crumbly scrambled eggs and shredded cabbage (plus some leftover menma). But that actually worked fine! If you have the choice, the creamy and spicy broth does go better with meat (or soy) than with egg, but it's nice to have options.
Anyway, definitely buying this again! I'd rate it higher than Soup No Tatsujin's tantanmen soup, but then again, that's maybe 1/3 the price, even without considering that it doesn't include noodles. In an ideal world, Nissin would start selling the soup alone so I could mix and match with cheap store brand noodles........
