Affordable lunch sets are hard to come by, even more so in the CBD. Thankfully, there's always Katanashi's Lunch Set ($12) to fall back on — this Boat Quay joint is just a short stroll from Raffles Place MRT Station. There are 10 rice bowls to choose from, and each comes with a side salad and miso soup. Go for the Unatama Don, grilled eel coated in a sweet soy sauce glaze, or the Chicken Teritama Don, deep-fried chicken drizzled with teriyaki sauce and mayonnaise, served with an onsen egg.
