It's Always Sunny in Philadelphia Season 8 Episode 9
The Gang Dines Out
Dennis and Mac are having their monthly dinner together at Guigino's, the finest Italian restaurant in Philadelphia, when Charlie and Frank enter and sit at a different table. The two roomies are celebrating the anniversary of moving in together. Meanwhile, Dee curses to herself, for ending up at the same eatery as the rest of The Gang and fears they'll catch her dining alone, but ends up never getting noticed. Instead, the two tables engage in a way of one-upmanship that ends with everyone getting what they want.
