Buffets can be questionable. After all, who knows how long the kung pao chicken's been exposed to the unwashed masses coughing, spitting and smearing their way through self-service? But luckily, Dynasty Buffet achieves its aim of hot, fresh and thoroughly edible Asian eats, with none of the ick factor. You can stuff yourself at this North Miami Beach spot with coconut shrimp, egg drop soup, tofu and vegetables, sweet and sour chicken, dumplings and sushi, all for a weekday lunchtime price of $7.55 (dinnertime $10.55). That's less than you'd pay for a a four course meal at McDonald's - and who knows where that crap's been.
