There is an ESPN Zone at both DL and WDW, but Tortilla Jo's is only at DL. I haven't eaten at the ESPN Zones, but I've been to Tortilla Jo's many times. I like it, but I've heard of some who really didn't care for it.
We just ate at ESPN Zone last Sunday for football, and it was CRAZY! We waited a good hour for a table, and that was at about 2 p.m. We got the nachos and they were YUMMY! We also got the ribs to share, and they were not good at all...really tough.
