One word of advice: Go before you're ravenous.The thing about dim sum is that you have to show up when everybody else in town does if you want to get the best, freshest selection of dishes.That means weekends are prime time at Phoenix Palace, when Asian families mob the place to gather at big tables and fill their lazy Susans with plate after plate of Cantonese specialties. Don't be surprised if servers pushing carts of food stop by your table before you've hardly sat down — they'll keep the food coming until you're aching for mercy. There's pork galore (steamed char siu bao filled with barbecue pork, dumplings filled with pork, and plenty of other treats), spicy chicken feet flecked with chile, turnip cake, shrimp-filled siu mai, translucent rice noodles wrapped around strips of golden pastry, spare ribs, and congee. That's just a tiny sample, but you get the picture. Go early, go hungry, and leave happy.
