Dinner recommendation near Reston town center
How many people?
Ice House Cafe is a nice small place over at the edge of old town Herndon. The others that quickly come to mind in a similar vein are Cafe Montmartre at Lake Anne, El Manantial in Tall Oaks, Euro Bistro, Three Thai Sushi, and Paradise Indian (these last three are all very close - with EB and PI being nearly next door to each other.
There's a new Japanese place, Nippon, that is also near those last three, and all four aren't far from old town Herndon.
