There are no authentic soups on the weekend
"The soup is more of a sign that a place is really authentic than a red flag. You want a menudo or pozole option on the weekend."
There are random Spanish words on the menu
"If you can buy a Mucho Taco Grande, if there's anything named like that, it's a bad sign. Or things like an Ole Burrito!"
There are bowls and lettuce wraps on the menu
"You can't have a taco without a tortilla. That's like Tacos 101."
There are ridiculous tequila rituals
"In Cancun, when tourists order tequila, they'll come and shake your head first."
There's a lack of Mexican drinks
“If they're limited to only American canned Coke, versus Mexican bottled Coke, that's a sign. You know it's real when they have options for aguas frescas.”
