Solo lunch - Cambridge / Somerville / Arlington?
I have a rare afternoon to myself, and was thinking about going out to lunch. This hasn't happened in a long time, so I was thinking about trying somewhere new. Where would you go for lunch by yourself in the general vicinity of North Cambridge? Spicy food and counter service are good (I don't like doing sit-down restaurants by myself). I don't eat pork, but am otherwise open to meat or vegetarian food. The weather is good enough that takeout might be okay too.
