Even I can survive on La Briutes for a couple days
Can also ask local hotels if they can import kosher food.
Did a 2 day stopover on the way to Australia last summer. Food was rough- some La briute, peanut butter and tortillas, tradition soup, lots of junk food and local fruit and alcohol. It still was a beautiful stop (stayed at IC and didn’t leave), although I wouldn’t go more than 2 days. It made us appreciate the food in Australia that much more.
