The only reason every burger aficionado in the bi-state area isn't lined up outside Dressel's is because, well, most folks don't equate "Welsh pub" with "perfect hamburger." But we know the truth, and it's killing us to keep the secret. So if you know what's good for you, you'll head Dresselward the next time the carnivorous craving kicks in. Start off with a nice beer -- a Double Dragon Bitter Ale, perhaps, or a Fuller's London Porter. Order a basket of homemade potato chips (and don't forget the side of eat-it-with-a-spoon-good rarebit). Then request the pièce de résistance, the Platonic ideal of a hamburger: charred and savory on the outside, meaty and pink on the inside, nestled on an ace kaiser roll with a thick tomato slice and romaine lettuce leaves on the side. And, because we're already divulging our secrets, hear this: No one will think any less of you if you put some of that rarebit on your burger. Truly.
