Temple Bar: 306 W. Champion
Temple Bar is one of my favorite spots to meet friends for drinks, and while they no longer list a vegan happy hour special on the menu, the staff there are really great about making something vegan upon request.
Their menu changes seasonally, so you never really know what you are going to get, but past choices have ranged from amazing salads with roasted carrots and cavier lentils, to pickled veggies, olives & warm pistachios, to a roasted cauliflower wedge drizzled with cilantro pesto. I love this place for socializing and unwinding, and I appreciate how they will always make something vegan for me, even if I am not sure what it will be until I ask.
If you are looking for a nice place to grab a little bite and enjoy a nice drink, Temple Bar is a great place to go.
