I haven't indulged yet, but I got a report from Wendy. She has been to Chipotle and Arbys but hasn't figured out what a vegetarian should get at Five Guys. Obviously, the burgers are out, although I think the Five Guys fries are what lift it over Fatburger or other competitors. Wendy noted that all three joints have limited menus -- less options, for example, than a standalone Arby's.
Yogiberry is still under construction across from Zales. Last I heard, they hoped to open in August 2009.
