🔮 After a catastrophic water main break on Sunset Boulevard in July turned Holloway Drive into a churning river and buried Dialog Cafe under feet of mud and debris, it looks like the cherished community hotspot may have found a lifeline — but it still doesn’t know when it will truly be able to return home. Dialog Cafe announced it will reopen Oct. 3 inside The Sun Rose West Hollywood hotel on the Sunset Strip, beginning a temporary residency with its full menu and, remarkably, the same team it employed before its longtime location was wrecked by flooding.
🔮 The pint-sized spot that Chef Willian Joo and his partner Jennifer So opened in LA’s Pico-Robertson area tied at number five, worldwide, beating out scores of Italian offerings — an astonishing feat that tells the world what Southern California diners already know. “So proud of William and all of our team at both locations working tirelessly to keep up with demand while retaining the highest quality possible,” So wrote on social media following the stunning win.
🔮 While In-N-Out boasts that its fries are made from potatoes that come straight from the farm, sliced inside the restaurant and cooked in 100% sunflower oil, that painstaking freshness can’t stop critics from savaging their texture. “They seem to taste like cardboard and they seem to take pride in how crap they are,” one disgruntled diner said on Reddit — echoing the feelings of many others, including superfan Hilary Duff — who once notably said that while In-N-Out would be her death row meal, she’d skip the fries entirely.
🔮 That event, promoted by Coachella creators Goldenvoice and set to star Olivia Dean and The Killers, was scrapped after surf and storm water generated by Hurricane Marie eroded a large portion of the festival site, according to SaMo city officials — though whispers of supposedly sluggish ticket sales spread quickly all over town.
🔮 Others offered a considerably less sci-fi explanation, arguing that he might have been European or a fashionable guy ahead of the curve.
🔮 Solvang specifically has had considerable beef with St. George, too, which could be one reason why his latest proposal was met with such particular ire — his downtown hotel project, the 1704 Mission Hotel and Cottages, was slapped with a stop work order over desired design changes, leading St. George to file a lawsuit against the city, SFGATE reported earlier.
