Nestled into the sterilized, gentrified corner of a strip mall in Plano, close to the lauded burger joint Five Guys, is the Holy Grail. (No. Not literally. That's the joint's name.) The Observer has blessed Holy Grail's dishes like the fried goat cheese balls and burger, but we've managed to leave out something simple: the soft pretzels. No, oh no, these aren't those bullshit things you get at Auntie Anne's. These are house-made, butter-brushed and kosher-salted bread twists. And they come with béchamel cheese sauce and spicy stone-ground mustard. Two people can take this appetizer down, or maybe one person with a sick hangover. Either way, one bite of buttery, soft, oven-hot bread with the cheese sauce, and you ain't leaving for a while.
