The Ebi Taigamori ($18++) was... Okay.
It was enjoyable on first slurp, but after a while, the double-boiled Katsuo Soup felt very one-dimensional & salty. The tempura batter is quite thick & oily, but the prawns inside were plump & good.
I somewhat liked the chewy texture of the udon, but I didn't find it particularly mind-blowing.
Maybe the other dishes are more unique & impressive... The menu is pretty varied with several types of Udon & cooking styles. I would consider trying them if I come back.
