Been eating here for lunch for quite sometime. Menu indicates an upcharge for adding an additional burger patty, gluten free bun, or vegan patty.
I simply got the Aloha Burger with grilled chicken instead of burger (grilled chicken is Always cheaper than beef, in any setting).
I was charged $1.50 for this. The MOST Expensive burger on the menu is $11.79....my CHICKEN SANDWICH (menu price $11.49), was a $15 sandwicg. This was an EXTREMELY UNSATISFACTORY & UNFORTUNATE customer experience.
