Can’t imagine the businesses in Allentown ever realized just how invasive construction would get once developers started treating the blocks just south of Mercer like a petri dish for concrete sea monkeys. Many local businesses bought into the neighborhood early and are now paying a price, which is putting it kindly. “Getting @#$%ed by the cancer-like growth that may be their success one day if only they can live through the dust” would be more accurate. Blue Moon Burgers at least appeals to the orange-vested construction crowd at lunch, and the chain is indeed locally owned. What’s special here are the fries, a thin-cut waffle fry that makes for a larger than normal amount of fry gut in the bottom of the container, but well worth it. Burgers are half price on Wednesdays after 3:00 p.m. if you purchase a drink and a side, which you can do if you can find a goddamn parking spot.The burger joint also uses all natural, local Painted Hills beef , a managed program of pasture-raised and grain-finished beef from nearly 70 different ranches in the Northwest. This means the beef eat corn, barley, and more for to six months before processing. Blue Moon Burgers, 920 Republican St. in S.L.U. and 703 N. 34th St. in Fremont)
