Iron Gate is a lovely cafe right on Washington Ave near the Armory.
It has a lovely patio, and great privacy from the world outside.
They have a great selection of beverages. (I tried a "dirty chai tea)
They have a wide selection of food, including several vegetarian option and many gluten free options.
I had their handmade black bean burger, and the Iron Goddess salad. Both of were were delicious, satisfying and with portions good enough for left overs.
