Wear sneakers and bring a light jacket. For Peking duck, head straight to Ziguangyuan and get their set meal for two – it's a real bargain at around 100 RMB. Their 'naipizi' (milk skin dessert) is also good. Near the Lama Temple (Yonghegong), there's a fantastic place for lamb spine hot pot ('yang xiezi') that costs just over 100 RMB, which is a good price. Their service is decent too, and you can easily find it with an online search. They stay open until 2 AM. Sanhe's hawthorn drink is also delicious, at 12 RMB per glass. I wouldn't recommend the shuan rou (instant-boiled mutton) if you don't like sesame paste; I usually make my own dipping sauce with sesame oil.
