CSB — Chicago Secret Burger Pop-Up 🍔

CSB stands for Chicago Secret Burger — a pop-up by a smash-patty specialist who’s gained a cult following for his elusive events. I’d heard about CSB for a while but never managed to snag one — the chef announces events randomly (like his last giveaway: comment a restaurant recommendation on his IG post, and he’d pick 100 winners).😘👍 This time, CSB partnered with speakeasy bar Nine Bar in Chinatown. Doors at 6 PM, first come, first served. I arrived at 5:30 PM — already 30 people ahead in line. Ordered at 6:15, got my burger by 6:40. 🍔 Verdict: It’s a solid smash burger — juicy, double-patty, tangy-sweet sauce and pickles. But not worth a 2-hour wait, and honestly not living up to the hype. For a great smash burger without the hassle, I’d recommend Three House instead. 💰 The $20 combo includes a burger, chips, and a cookie — good value.
