Right down the block from MOCA is one of the biggest rice box combination restaurant I’ve ever seen.
For $4 you can get a takeout box with 3 dishes, rice and a soup. Dine in is 50 cents more. Guess this is not really a “buffet”. There is a huge number of different dishes at this place. I’m not going to name them all, but just take a look at the pictures. Surprisingly many tourists know about this spot, probably because it’s right off Canal St.
