What car are you picking up??
I am not too far in Bethesda actually! Not much to do in Germantown other than a few nice bars. But Carrabbas is nice if you wanna sit down, or you could hit up 118 (Germantown Rd) and find Safeway, CVS, tacobell, or across the street you can find California Tortilla, starbucks, etc. There is also Germantown Plex (or whatever it's called) that has a water park, outdoor tennis, soccer, ever damn thing you could think of!
