Nathans is in the heart of Georgetown. If you pop in here in midafternoon, it's a quiet place to grab a beer or glass of wine and watch the action on the street. Visit at night, though, and it's a more typical bar scene, crowded with locals, out-of-towners, students, and a sprinkling of couples in from the 'burbs. That's the front room. The back room at Nathans is a civilized, candlelit restaurant serving classic American fare. After 11:30pm on Friday and Saturday, this room turns into a dance hall, playing deejay music and attracting the 20-somethings Friday night, an older crowd Saturday night.
