The Radical Reuben will cost you less than $5 on Thursday. (via Chicago Diner)

Before 1983, if you went to a Chicago diner and ordered a meatless reuben, you'd probably have gotten two slices of bread with some cheese and sauerkraut stuffed in between (not to mention a lot of dirty looks).

That all changed when the Chicago Diner opened, offering not only radically different reuben sandwiches but lots more comfort-food made with vegetarian/vegan ingredients. Next week, the Boystown landmark celebrates its 27th birthday by offering select sandwiches for $4.95 each and drinks for just $3. The best news: you don't have to get in a 'Hot Tub Time Machine' to enjoy these flashback prices.
