Afghani food is an interesting intersection of Middle Eastern and Indian influences, with more subtle seasoning than either. Delray Vietnamese Garden has solid Vietnamese cooking and the staff is extremely welcoming - it's more home cooking than the refined menu at Taste of Saigon in Rockville. One of the friendliest places we've found. Delhi Dhaba is a big favorite in our house. Last year's renovation improved the atmosphere by a long shot, but the prices are still very reasonable.
Butter chicken is a hit with our three year-old, along with mango lassi.
There are always specials worth trying, including goat many days. The mix and match selection is the best deal. For sophisticated Asian noshes, go to Raku - meals very carefully prepared and beautifully presented. They do experimental fusion and traditional sushi equally well. For down-home Japanese food, we go to Hinode and Matuba .
