Tucked into an easy-to-overlook Chinatown basement, Best Little serves traditional Cantonese and Teochew dishes at ridiculous bargain prices. Its simplicity, freshness and ringing clarity of flavors will seduce the most timid American accustomed to falling back on General Gau’s. Bring a friend or two and start with minced beef soup with Chinese parsley, then salty pork with green beans, a lettuce-wrap dish that will make you regret ever stepping inside a P.F. Chang’s. You’ll be back, and soon.
