I'm moving to Silver Spring, MD in early February. I'm sure my new colleagues will have recommendations for dining options, however I'm turning my palate over to those of you who live in or travel to this part of the country. Can anyone recommend some inexpensive/ moderately priced places for sushi, Mexican, Ethiopian, Middle-Eastern and pizza? I'll be dining solo until I meet some new friends, so take-out might be helpful. Thanks in advance for your help!
