Big, bright, sparkly clean, lots of pumps, with beautiful cashiers and friendly service, yada yada--that's not why this is the best pit stop. It's the best for one simple reason: The owner is oddly obsessed with selling the coldest, cheapest beer in Dallas. The beer is already chilled to 36 degrees. As Best of Dallas was going to press, Lakewood Mobil was undergoing major reconstruction to create a special "ice-cave" at the back, where the beer will be chilled to 26 degrees--still liquid, but the bottles might freeze to your fingers. They sell all the hard-to-get cigarettes--Esmir Stingers, Kents, Dunhills--and they have a pretty decent wine selection, too. Not bad for a Mobil, eh?
