This airy covered all wood and bamboo beer garden right at the front of the Silk Road Dunhuang Hotel carpark serves up cheap, cold bottles of Tsingtao (¥15) and heaping portions of fried noodles and grilled meats. It's a bit noisy as it's right next to the main road, but it's a welcome refuelling point after hiking up Singing Sands Dune.
Note that the name on the front is spelled Gebi Bros Grill House, which is a misspelling of the pinyin.
