At Sukhumvoth Soi 11 there's a really superb tapas restaurant. But for me, the highlight is the side street: There you'll find many restaurants. This gives you a very wide choice of eating options and the street is for pedestrians only. It's really relaxing to sit outside there in the evening. There's also a few bars where you can get a nightcap. But it tends to be busy, so it's not really the quietest place in the centre of Bangkok. But what is quiet in this city?
