"I'm ashamed to admit that, even though I'm a naive Tulsan, I had not visited Brownie's until recently. It has an old school diner/burger joint feel. I ordered the classic double, fries, and, of course, a frozen mug of root beer. The burger is simple, but satisfying. The fry basket was quite large and the fries are good. If you come here, though, you are probably here for the root beer. The servers walk around with pitchers of the delicious drink, so if you're not careful, you'll enjoy enough to regret it later! It's sweet, light aftertaste, refreshing. I highly recommend giving this place a try."
