ChiengMai in Fairfax City (downtown) is pretty good and not too expensive.
 Same menu at lunch and dinner (except for two or three lunch "specials"
which
 aren't very special--at least in the sense that they are the same every
day).
 Dinner will probably run about $10-12 per person, depending on whetther one
 orders an appetizer and/or dessert and/or beverage.  Tax and tip extra. 
Lunch
 can easily be had for well under $10.  You may have some trouble convincing
 them that you really want your food cooked HOT, but with some luck, they
will
 bring you a condiment bowl of crushed ground pepper.  I like their beef
 mussamun and their satay appetizers.

Tara Thai is a new place just west of the center of Vienna, on Rte 123 (W.
 Maple Avenue).  I haven't been there yet.  Looks fancy, though; probably
 pricier than ChiengMai.
