I'm looking for great food in Bethesda - not a fancy meal, just a yummy hole-in-the-wall would be fine - and not a chain. I'll try David Craig and Black's one of these days, but right now I am looking for something low-key. I was thinking of Louisiana Express but have seen recent posts that it is going downhill. How is Pizza Zero? Love ethnic food but have not found anything wonderful in Bethesda yet. Does anyone know of any hidden gems?
