We stayed just two doors up from the Sisaket in the Gat Point Charlie so it would have been rude not to try the Sisaket, especially as the Trip reviews are so good. The restaurant didn't disappoint. It has a very pleasant ambiance and feels like quite a small intimate place even though it extends back a long way from the street. There's an outdoor patio area as well as tables on the pavement but it was too cold to sit outside. We were greeted by friendly waiting staff in beautiful brocaded silk costumes and seated quite close to the entrance. It wasn't busy when we went so I can't comment on how it would be at the height of the season. We didn't have a reservation but I'm sure this would be a must at busy times. The menu is very extensive but printed in German, English and Thai so there's no language problem. All the spicier meals are marked eith the standard chilli symbols. We picked up a leaflet of the menu (plus it's available as a PDF from their website) which meant that we could choose in advance. We ordered a bit too much food (one shrimp, one duck, pork ribs and fried rice with chicken) but that's always a danger with East Asian restaurants. We didn't need the fried rice as all meals come with steamed rice. This was pointed out to us but hey we like fried rice. I think a good guide is probably one dish per person in the party plus maybe fried rice. The food was amazing - delicious, fresh, full of fabulous flavours and so beautifully presented. For example, our shrimp dish was served in a whole coconut with the hard shell removed and the duck dish came with a small duck in flight sculpted from hard bamboo shoot. The total bill including two small beers and a tip came to about €64 which isn't cheap but we thought was pretty good for such a fantastic meal. Would love to eat here again if we ever return to Berlin.
