Do not bother if you're up for buffalo sauce, go somewhere else.
Six pieces of crunchy fried chicken in buffalo sauce for $18. The coating isn't complete but there's an okay amount of sauce. Russ says the sauce is way too sweet, has too little heat, lacks the vinegar twang and is almost like mayo. The 3/10 on screen matches what he says.
