Here is an ad poster for "D * Lounge"
Just what that is, is unknown. (A regular restaurant, a pop-up theme cafe?) However, the "recommendation" here is a selection of chili dogs for 300 yen. )Cheese appears to add 20 more yen. There's a CG Sonic at the bottom, holding a chili dog in one hand, and a drink cup that's D Lounge branded in the other. The first word in the black text of the ad says "Sonic", so maybe it describes a theme too?
