Target the post-5pm window specifically to take advantage of the twenty-percent drinks discount on dinner service. The specialty coffee is the strongest daytime order and holds up against dedicated coffee bars on the soi. Pair a Chu dinner visit with an earlier stop at Treehouse Cafe on the same street. A dependable all-day option that rewards knowing the discount structure before you arrive.
Chu sits at 18/1 Sukhumvit Soi 31 in Watthana. It is a modern cafe and restaurant on the same soi as Treehouse Cafe. The space operates across a clean interior with a menu covering coffee alongside brunch plates and a full dinner service. Chu's dinner offering applies a twenty-percent discount to drinks ordered after 5pm, creating a dependable happy-hour structure for the after-work crowd. The 4.4-star Google rating across nearly 2,000 reviews shows a consistent performance across both daytime and evening service periods. Coffee quality meets specialty-level expectations during morning service, and the kitchen handles western-style brunch dishes with an equally reliable output. The evening menu shifts toward more substantial protein-led plates appropriate for dinner. Natural light fills the ground floor seating during the midday window, and the interior handles solo visits as comfortably as group bookings. Soi 31 runs parallel to Sukhumvit and carries less foot traffic than the main road. The calmer street gives the cafe a different atmosphere from venues on the primary strip.
BTS Phrom Phong connects to Soi 31 via a short walk from the station exit toward the odd-numbered sois. The 20% drinks discount after 5pm is the strongest single reason to target this venue for an evening visit over nearby alternatives. Reservation is generally not required for weekday evenings but is advisable for groups of four or more on weekend dinner service.
The brunch menu covers eggs and toast formats alongside smoothie bowls and lighter cafe bites. Staff handle dietary requests in English without difficulty throughout the full service day. The Soi 31 location clusters Chu with Treehouse Cafe and several other strong options. The street is reliable for multiple cafe stops on a single visit. The twenty-percent discount on evening drinks is not advertised widely and frequently surprises first-time visitors who arrive for dinner.
