I agree with shnda99.
Go check out Pam's Chicago Style Dogs and More down in the Loop.
They are the cleanest hot dog joint I have ever been in.
awesome Chicago Dog's, Gyro's, Italian Beef Sandwich's and just about anything else.
Everything is authentic Chicago ingredients.
They also did the catering for our company picnic in Shaw Park about 3 weeks ago!
Check them out and let me know what you think!
