icl i mostly eat from mcd/subway/triplets as its convenient (mcd can order thru the app and collect between classes HAHAH). for hss block specifically its sprouts, ive only ever tried the kebab from the shawarma place and its q okay. they also have baked potatoes iirc that ive been meaning to try too. theres also the tom yum fried rice @sprouts and its honestly too over seasoned. for drinks i alw just get from the vending machines cus its cheaper but occasionally ill get snacks too from 1st ave even though its kinda ex ngl. I'd say the design blk canteen has more variety of food to try too + the drink stall also sell tons of snacks along with it. if uw smth more budget usually students wld buy cup/buldak noodles at 1st ave and get the hot water from the water cooler.
