This small fast-food place offers wild game sausages (plus standard dogs and burgers) that are just excellent. We have now tried four different sausages and all I can say is wow, this place is good. The varieties available on our recent visits were elk and pear, pheasant and cognac, wild boar, and duck and orange, and each tasted distinctive and each was delicious. VERY delicious. One night, we tried a foie gras sausage special - also excellent. I understand the chef (formerly P. Diddy's chef! really!) will be offering special items every week in addition to the usual menu. Unusually for a place that focuses on dogs, the burgers are out of this world too. Your sausage comes on a good, simple bun, with tasty truffle fries. The staff is very friendly and helpful, the space is tiny, and the setting is casual, a little eccentric - funky music videos, a solar system theme on the tabletops. Be prepared to walk down (and then up) a flight of stairs.
Heat is in the site of the former Underdogg, downstairs under Flash Taco at the hipster epicenter of Damen, North and Milwaukee. It opens at lunchtime and it stays open very late. Also, I understand that Heat delivers until the amazing hour of 4:30 AM.
GO NOW before the lines get crazier than at Hot Doug's.
