I effing love wonderdogs. It's a bit of a hole in the wall place loving cared for by a family team that serve you delicious, delicious hot dogs regularly with a smile. On top of that, the food is fast, cheap, and delicious. I tried my first Chicago style hot dog here, and found myself surprisingly delighted by the excessive vegetation.
My other grad friends and I love this place so much that we've formed a ridiculous HDC (Hot Dog Club) to celebrate the joys of the frankfurter on Fridays. Where else should one go but Wonderdogs? I personally enjoy a marvelous Wonderdog itself--which is a chili cheese dog, no frills--with a side of fries. It's a great, quick lunch, and it brings a smile to my face every time.
Thanks Wonderdogs, for putting up with ridiculous, hungry graduate students. :)
