Vera is a great spot for small plates in the West Loop of Chicago. We've stopped by several times, and each time the menu is different. Their Vegetable section isn't completely vegetarian, but you can always find veggie items and a lot of dishes can easily be veganized.
During the summer they had a Strawberry Gazpacho with onions and garlic that was so good. Really unique flavors and very complex.
The Grilled Zucchini with romesco sauce, basil and hazelnuts was also pretty stellar.
They also have Papas Bravas (ordered without the mayo) - super salty, crispy and delicious. Their bread is always served warm and with a strong olive oil. Great place for a snack.
