I am not a big horseradish fan, but I would eat it before mayo. I do love spicy mustard in general.
Your meal there looks good, though.
If you’re ever in Buffalo, one of those is a must, along with genuine Buffalo chicken wings and pizza.
At the place I worked before I got married, the salesmen who came through LOVED to have Buffalo as part of their territory because whenever they came into town, they’d treat their customers to dinner and would be taken to Buffalo’s best restaurants.
Buffalo may not have a lot going for it in many areas, but in food, there is no comparison. They know how to eat.
