With all honesty, I've never heard of 'mentaiko' before. The first time trying Mentaiko fries just made me fall in love with it. Not a fan of fries because I'm not a potato lover (plus fries reminds me of macdonalds fries which is extremely unhealthy). To add on, I absolutely dislike mayo because I hate anything that is creamy or mayo-y taste (if I'm right to say that mayo is creamy?). But Mentaiko just made me break this hatred because it's mixed with mayo (say whuttt). Okay basically it's the sauce that is so addictive that even a person like me will keep craving for it. Bottomline is, Grub has wonderful side dishes.
