About
Zaap One Ratchada is the big Isan restaurant across the road from Big C Ratchada. TrueID's list of Ratchada and Rama 9 places for after-work eating includes it and names som tam and grilled chicken as the things to order. Google lists hours of 10:00 to 23:00 daily, while the 2018 TrueID article gave 22:00, so expect the kitchen to wind down earlier than the posted close. It scores 4.2 on Google from more than 2,100 reviews. The restaurant sits in Huai Khwang district within walking distance of MRT Huai Khwang, and it is the obvious stop for anyone who has parked or shopped at Big C and wants to cross the road to eat. Prices are standard Isan-restaurant level, and tables of four to six ordering several som tam variations to share are the norm. Its Facebook page goes by ZaapOne.
