Okay, I've been to this place in downtown Brooklyn three times now. The fried fish, fried shrimp, and french fries are REALLY good, and really cheap!
The only questionable things I've had so far were the fried scallops (a little tough) and the fried vegetables (a heavy, nest-like tangle of deep-fried onion/carrot/green pepper strips, too much fat given the thinness of the strips).
Overall, I still think it's a good option if you're stuck in downtown Brooklyn for lunch.
Lambretta, I would like to hear your opinion, if you ever get the chance....
