I've only heard a couple rumors. I know they were supposed to open a new place downtown, but according to a couple sources they will only be serving their famous sandwiches. Maybe they're just waiting for their new liquor license.
One person told me that they were going to sell just gourmet popcorn.
Edit: After some research it looks like the building that was going to be the new Clark's is now a gourmet popcorn shop, but they still might move the bar into the location and relocate the popcorn shop.
