Rice Paddies Grill (across from Women's Market-besides Starbuck's) has pho. I have never had it before, but have liked the 2 other items I have ordered there. Maybe worth a try...If you do...please report back!
I've had their pho several times and think its very good. Definitely the best you'll find in Bethesda. And if you haven't tried the Indian carryout in the Women's coop you should. Her $5 combo is a steal.
