For a first date, the Reef covers all bases: low lights and quiet music, a second-floor view of Adams Morgan’s street scene, and an eclectic, cheap-without-tasting-cheap menu. Ask for a table near one of the aquariums but don’t get hung up on fish when it comes time to order. Land-based dishes are best. We’re partial to the mini pulled-pork barbecue sandwiches (two for $5, four for $7, six for $9), and the moist, cumin-scented veggie burger ($10) with its heaping side of fries. The staff practically lives off the Monte Cristo sandwich ($9).
