My experience eating at Chicken-in us mediocre at best. Firstly, the seating is far from comfortable - long wooden tables and wooden benches with no backs. Seeing as this is mainly fast food, this should not have been a problem except the food did not come quickly (contrary to a previous review). We came in on a weekday afternoon when there are only 2 other parties (one of them already done their food) and somehow food still took about 30 mins to arrive.
Beyond this, the menu has a lot of options for fried anything in addition to chicken. Their fried items come in little paper bags you just eat out of - much like night market style. I'd much prefer my food at a restaurant to come on a plate.
Luckily, the food itself was decent. Fried items were very hot and flavourful. Hopefully they develop a more attractive lunch combo menu (currently just 2-3 be to options) and increase the quality of their drinks.
