There is this Japanese restaurant near my office that I really like. I've dined there like 3 or 4 times, and every time I leave the restaurant feeling very happy about the food. Ootoya is the name, and it's located at B1 Suntec City Tower Three.
You can order green tea hot or chilled here, and it's free flow throughout your meal. Not only that, steamed rice and soups are also free flow! The thing is their food portions are not small, so very few people would actually ask for second or third helping of rice or soup anyway.
Condiments can be found on every table in pretty porcelain containers - Chilli flakes, ground sesame seeds, soya sauce etc.
All of my friends love the food they ordered. Every one of them looked good, I say!
Be prepared to spend at least $25 when you dine at Ootoya. But I feel it's worth it because the quality of the food is good, and the portions are generous. =)
