Once Again Hostel, the hip hostel in the Pratu Phee neighborhood and devoted local business supporter, has just released a food delivery platform called Locall, which focuses on local food stalls in street food hubs like Yaowarat, Nanglinchee and Pratu Phee. Everything is done by locals, from cooking and packing to delivering (in this case, by motorbike taxi). 
The initiative has been up and running for a little over a month, and it has already received tremendous feedback. Locall is now delivering to 23 districts in Bangkok—Klong San, Wattana, Phaya Thai, Bangkok Yai, Pathumwan, Sathorn: you name it.
Orders can be placed via Line @locall.bkk (a minimum order of B300 is required), with delivery fees are starting from B30 (additional B7/km). Available from 10am-7pm.
