Affordable Japanese Food

I just came back from lunch and was pleased to find a new place with relatively affordable Japanese food. A nearby shopping mall had a whole area filled with Japanese stalls in the basement with affordable Japanese meals. I had a nice little mini rice don with around 4 pieces of fried chicken for an affordable $5! My colleagues thought it was too small but I found it just nice. I'm funny like that and often prefer eating smaller portions so I don't feel too greedy and overeat!
