Obento lunch at Nanbantei

Previously I have had a similar yakitori obento lunch set from Kushigin. Now that I'm having it at Nanbantei (Far East Plaza #05-132, 14 Scotts Road, S228213), I realised that they are exactly the same thing and cost the same amount. A $12.50 bento box with 5 sticks of grills, pickles, rice topped with minced chicken, sauteed mushrooms and seaweed. The difference between the two bento boxes are probably just the rice that is being used and as I recall, the former didn't use the short grained Japanese rice. Otherwise, lunch at both places (same management if you didn't know) are pretty much the same deal. Now I'm not too sure why I was expecting any differences at all.
