If you’ve spent as much time eating noodles as we have, you probably have wondered what it’s like to put fusilli in your kuay tiew. If so, you’re in luck because 1000 Zen has done those edible experiments for you already, saving you trial and error and a possible bad stomach. 1000 Zen — a play on the Thai word sen, or “thread” in English — lets customers choose what to put in their bowls, with multiple options of noodles, toppings and soups. After the success of its first branch in Ari, a second opened in the Sathon area two months ago. We stopped by to play god with noodle dishes. The shop looks like a café on the outside and tries to make up for its small space with floor-to-ceiling windows and mirrored walls. But during lunchtime, customers will literally be rubbing shoulders.
