Fat Head's Southside Slopes sandwich made an appearance in the in-room touristy magazine at the Marriott, and the ad was effective as hell-- once you lay eyes upon this animal, you know right away that your life will be incomplete without trying one. It seemed as though every beer advocate in town congregates here, and with good reason... despite the huge crowd, the tap list is an all star roster of fine brew at decent prices. The Southside Slopes was the star of the show, however. It's a beast of a sandwich with cheese and grilled onions atop pierogies and kielbasa. It starts out very good, with the kielbasa dominating each bite. It gets even better as time passes, with the cheese and pierogies melting into a creamy potato concoction that wonderfully complements the sausagey overtones. Trying to finish might make you uncomfortably overstuffed, but that doesn't make each step of the attempt any less of a religious experience. If you're in Pittsburgh, it's a must-do.
