I went on St.Patty's day for a free shamrock shake and got the famous burger. It surprised me! I really loved it! (Mind you it put me in a bit of a coma for the next 24 hrs but well worth it!)
The onion rings (which so many people raved about) were not what I expected though, too doughy and greasy, I couldn't even finish more than 2 and that NEVER happened to me before with onion rings.
Would definitely go back for more of their burgers!
