Decided to try the Deluxe Tendon since it’s exclusive to this outlet. In addition to the usual oozy egg, prawn and chicken, it also comes with snow crab, squid and conger eel (we thought this was a smaller unagi fillet as it still has that familiar brackish taste).
Would probably stick to the Special Tendon next time, although the chicken pieces seem thinner (and are thus less juicy) than I remember.
