The good news is that you can feast on wonderful fresh seafood (fried squid, steamed whole flounder, pepper and salt roasted prawns in the shell) until all hours -- well, 3 a.m., which is late indeed in our fair city -- in this underdecorated but picturesque corner spot in North Beach, where you might even be able to find parking in the wee hours. The bad news: It's cash only (so remember to bring some, because there's nothing worse than showing up hungry for crab with ginger and garlic at 2 a.m. and finding only a credit card in your wallet) and closed on Tuesday.
