Finally got to try this beef bowl at MOE cafeteria ($6.50) and it's..... Worth it!!! Cuts are of great quality and they have interesting sauces like Wolfberry Wine. (maybe I could try pairing with the truffle one next time). With 3 veggies and 1 onsen egg: the day's nutrition is definitely clocked.
Be warned though, the queue to enter the cafeteria at lunch time can be pretty long
