They could make both large and small portions.
Also the quality of the chicken seems inconsistent. The other day I bought a whole cooked chicken at the Milliken location (the huge yellow ones with ginger/green onion at $4.99 or so) and it was tough to eat and very dry. Didn't even have taste when I cooked with noodles afterwards (removed skin of course). I guess you get what you pay for! I should have picked the smaller ones ... LOL.
The prepared spicy large crab at Warden location however was very good. I pick one up everytime I'm there late at night when it's reduced to $5.99 or $6.99 (did it go up in price lately?). I love lobster and crab!
