California burger chain In-N-Out is hosting a one-day pop up at Siam Discovery this Nov 9, and it’s only 4 hours. 
Quietly slipping into town, the much-loved chain will be flipping burgers from noon to 4pm at G/F. 
As seen from its last pop-up 4 years ago, you may need to rush there ahead of time if you don’t want to see a “sold out” sign hanging at the store.
Nov 9. Siam Discovery. Noon-4pm.
