I am from Hawaii and have spent many days eating real thai home cooking at my friends houses. Spent several years in Thailand as well as laos and much of southeast asia. This food is definitely made for the locals here. I doubt the owners of the restaurant cook like this at home. But you have to do what you have to do to survive in the market you're in. Unfortunately, the food is bland, lacks that heat I'm used to. I thought the Som tam was ok, better than the rest of my meal. most of the other dishes I sampled with my family were bland or watered down.
Our waiter was not the greatest, but the owners and greeting staff were very friendly. They have really inviting decor and a massive fish tank to keep the kids occupied.
Prices were ridiculously overpriced for that meal. There's another thai restaurant just down the street, Samui thai that was much better. It had much better food and a little cheaper. The Decor at Samui is not nearly as nice as rainbow garden, so if that's what you look for rainbow garden is the place for you. I am out to eat so food is top priority for me.
the Thai food in Germany is probably some of the most expensive thai food in the world next to some fine dining thai restaurant in New york possibly. Samui will probably run you around 50-60 euros for a family of 4 where as Rainbow garden will cost around 80+ euros for a family of 4.
In hawaii an amazing hole in the wall authentic Thai restaurant will cost maybe 20-30$ or 15-20 Euros for a family of 4. But yes, we are far from asia here so up go the prices, and cost of living factor, I understand.
