Wow, just look at these reviews from Kraze Burger, who charges $1 for tap water:

“Terrible. Do not visit for any reason”

“Absolutely the worst burger I have ever seen or eaten”

“Greasy, flavorless and overpriced”

Alternative: Brewerkz for a good burger, but not in MBS. In MBS splurge just a bit more and go for Pizzeria Mozza
