Chamoun’s Rest Haven has a killer southern-style breakfast, along with the great Lebanese and American lunch and dinner. Highly recommended. Abe’s ribs are the best. Delta Amusement has great sandwiches, w/hand-carved meats. Only time I ate at Ground Zero was during a festival, and it was some of the WORST food I’d ever had. Even if I go back when they have the regular menu, I’ll refuse to eat there in protest. Wonderful place to drink a beer and hear some tunes, though.
Have a blast in AK! Haven’t been to the KBB fest yet, really want to someday.

Oh, if in Clarksdale, you have to stop at Cat Head Blues and Folk Art. Very cool.
