7-Eleven

Khao San’s round‑the‑clock lifesaver. Step in from the heat and motorbike horns to a blast of ice‑cold air‑con, bright aisles, and zero fuss. This branch sits mid‑block on Khao San Road and does exactly what you want at any hour: water for the walk, a caffeine hit before a temple day, and a salty snack after a big night. Regulars go straight for the ham‑and‑cheese toasties pressed on the spot, steamed buns, microwave curries, and bags of spicy chips. The coffee machine turns out reliable Americanos and Thai milk tea; the fridge is loaded with Leo, Singha, and Chang (alcohol sales follow Thai hours—no sales mid‑afternoon). Expect 24/7 service with quick queues, fair prices, and the little conveniences that keep a Bangkok day moving. Practical wins: ATMs right outside, mobile top‑ups at the counter, and cold electrolyte drinks when the heat gets real. It’s also the easiest place to grab sunscreen, paracetamol, or an emergency poncho before a storm rolls in. Open 24 hours, seven days a week.
