I love that they are staying open till 11pm. That's a great start. I wish more places downtown would stay open later. It seems there is a lack in businesses open between 4pm-9pm. The downtown seems to die a little after the office buildings close and before the clubs open. I wish that Caffe Ritazza would stay open later. I would love to grad some coffee after I come out of a club. Hopefully if the hours work at 5Guys more places will follow, then hopefully they start to venture into even later hours. I would love to see more places open till 3 or 4am, grabbing that after party crowd.
With 5 Guys opening downtown is getting a lot of name brands finally. Maybe next we will see a few name brand sit down restaurants coming back downtown. I wouldn't mind having an Applebee's, TGI Fridays, or Olive Garden in downtown. IMO it would actually help the to bring the tourist back down there. Having some name brands they recognize could give them a safe bet downtown if they aren't feeling as adventurous. 5 Guys though already helps this and provides a nice cheaper alternative to the many fancier restaurants downtown.
Having more places open on the weekends should help also. Saturday mornings can get pretty dead downtown, hopefully having a few more options helps bring more people down. I still think 55W though needs a few retail options now. It seems to have gotten the food covered, now they need to work on some shopping. Maybe an Urban Outfitters (downtown really needs one!), a Diesel shop, and a Rugby Ralph Lauren (why doesn't Orlando have one of these yet!?!) with its cool cafe.
