Ethiopian feasts are social events, a great excuse to corral a large group — friends, lovers, even adversaries — to share all the homey comfort food that's loaded on tables usually too small for all this largesse. At Nile Ethiopian, a moodily lit, spice-scented restaurant with plenty of groups, diners don't waste any time tearing off a piece of floppy injera — the Ethiopian vessel on which everything is served — and scooping up gently spiced lamb tibs, raw minced kitfo tartare and chicken wot, a mellow stew of lemon-smooched chicken, ginger, garlic and red peppers. Your best bet is to go with one (or both) of the combination meat/vegetarian trays, which journey through the exotic Ethiopian culinary lexicon.
