If you decide to pay this Uzbek hideaway a visit, be sure to go on a Friday or Saturday, when a resident belly dancer does her thing across the room all night long while music blares and an oversize flat-screen TV loops video of a fireplace. Secure a bottle of vodka — this could be a long night. Luckily, Chayhana Oasis serves plenty of deeply satisfying food representative of not only Uzbekistan but also the entire central Eurasian region where the former Soviet republic today traces its borders. Hence, a meal might begin with the tender stuffed Turkish-style grape leaves called doma ($12) and proceed to kovurma lagman ($15) — fried, house-made egg noodles flecked with chewy bits of beef and bell peppers topped with an impossibly thin shredded egg crepe. Later comes another western-Chinese-style salad: chopped cucumbers and minced meat tossed with soy and garlic, then sprinkled with a flurry of sesame seeds. Of course, there's no shortage of lamb and tender, chewy fresh-baked bread to soak up that waterfall of vodka. It's going to be a good night.
