If you like that special ingredient chili, and you aren't one of the ignorant about the origins of chili (like basically anyone from Texas) give Skyline a try.
I had the Loaded Bowl and a coney on the side. And both were very good. The dog is quite small and mostly helpful as a chili sop. The chili is good with plenty of toppings (in fact too much shredded cheddar cheese is my only complaint).
If you like hot sauces you'll walk out with a bottle of the Skyline Hot Sauce. Hotter than Franks or Crystal, more in the tabasco range but not as sharp with good flavor for both heat and vinegar.
For the slob in you they offer free Skyline Bibs with your meal.
Pros: great chili and awesome hot sauce.
Cons: believe it or not: too much cheese.
