Kapitein Zeppo's
You can sit outside in the small romantic alley where it is cool even on hot summer days. The restaurant has a transparant roof that can be opened when the weather allows it. On Sunday there's live music on the stage in the bar area. Once a month there's a cabaret.
The ambiance of this place is hard to describe...it's different. Go and see for yourself.

Café Roux The rooms of the prestigious hotel 'The Grand' (former city hall) are surrounding the charming inner garden where you can dine on a warm summer evening...very romantic! The atmosphere there is quiet and peaceful; a real heaven in Amsterdam. Keep a space open for the port and cheese tasting! Of course you also can have diner inside in the art deco interior design restaurant.

Reguliersdwarsstraat
In this street is where you will find many nice (and rather expensive) restaurants, like: Het Tuynhuys | no. 28 (great inner court terrace!) Garlic Queen | no. 27 (all dished with garlic!) Le Pecheur | no. 32 (specialized fish restaurant)
