Why no Greek food in Beltsville/Greenbelt/Lanham?
Okay, so I've had Carribean, Indian, Mexican food in the area. Dining companion doesn't like Chinese so that's out. Why no Greek places around?!
There's always Marathon, the Greek deli in College Park with good gyros. I believe that Plato's diner (also in CP) has some Greek specialties on the menu, although I can't personally vouch for them.
In general, the best places in that area are Korean, Vietnamese (pho), and Mexican.
Because the ethnic foods tend to follow the ethnicities of the folks who live there. Not a large Greek community in PG, though there used to be in MoCo.
