We're looking for someplace for Saturday night where four people can have fabulous food and a conversation at the same time. Two NYC 'hounds are taking friends (now living in Pawtucket) out for dinner. New Rivers, Cafe Nuovo, Gracie's, Broadway Bistro, Hemenway's, La Laiterie all sound really good, but we don't necessarily need something fancy or upscale. If there's, say, a casual Portuguese place you go to again and again, or that little taverna that's cheaper than the flight to Europe, even better. Any suggestions?
