Found a mentaiko place in Taipei! Will be going back to this restaurant again when I that occasional craving for super salty fish roe. Undecided on the other food (including the beef offal hotpot) they serve here, but the mentaiko was not bad at all!

Here's Kevin who happily skipped class so I wouldn't have to eat alone. He had the 明太子茶漬け, which was delicious!
