Zoe's Kitchen -- multiple locations in northern Virginia --
Our allergies to accommodate: peanut and tree nuts.
We do not eat desserts there, but have been able to eat the rest of the offerings (although one teen skips the pita as he feels it may be a risk & we just don't know -- I'm fine with that).
Good food, not the cheapest, but pretty fast & nice change of pace!!
We go to the One Loudoun location regularly. DD has egg allergy in addition to peanut and tree nut. She's safely had the hummus and pita appetizer and the grilled chicken entree (with a Greek salad instead of beans for the side).
We also do not eat dessert there. We usually have dinner there before going to the Alamo to see a movie. At the Alamo, DD has had the popcorn (with real butter) and Sour Patch Kids (though they are repackaged in a Chinese food style box) safely.
