I've used the Alexandria location many times. They always have some veggie options, and you can always omit a nut ingredient. If you've got folks with severe allergies, you might want to check, as I guess their could be a chance of some oil, residue from the nut jar/bowl getting near another one.
Definitely go to the website, and you can get a sense of the menu.
I've used them many times and liked them. It's not necessarily a huge price saver over some take out options, but if you'd like to serve more homemade meals, or not be frantically trying to scrounge around for ingredients, it can be great.
