老太太烧烤原是在松北电影院下的小烧烤摊，随着松北电影院片区没落，烧烤店移址，从此“奶奶”的院子里便有了秘密——放红色电影。老板房哥每年都会在院子里用老放映机放红色电影，这是情怀，也是奶奶院子里的独特魅力。

The old lady’s barbecue was originally a small barbecue stall located under the Songbei Cinema. With closure of the Cinema, the barbecue shop also moved. Since then, there has been a secret in the "grandmother"'s yard-showing old Chinese movies. Fang, the boss, will use the old projector to show old movies in the yard at the beginning of June every year. For him it is not only the way of preserving the unique environment but also a way to give Old lady’s barbecue a unique charm.
