Stack'd just might have the best vegetarian burger in the 'burgh. It's homemade, and either fried or baked to have a super crispy outside.
As other reviewers said, the best part about this place its the choose-your-own-adventure type of menu. Unlimited different sauces to top off my burger? Don't mind if I do! You get a giant burger and you can add a generous heaping of fries for $1-2.
They had several beers on tap and more in a cooler behind the bar. I really enjoyed the food and will definitely be back.
