Nestled in a shopping center in Plano shared by Five Guys and a kick-ass butcher is the Holy Grail Pub. Aside from having a damn good burger and one of the better curated craft-beer menus in North Texas, it features a bar snack that's worth the trip: baked bread twists (they call 'em pretzels) with a spicy mustard and house bechamel sauce. Come on; there are few things better than butter-washed, kosher-salt sprinkled warm bread in house-made cheese sauce. Right? The tall booths will let you devour it in peace.
