No guide can fully cover all the wonders of Amsterdam. Frascati is one such hidden gem. Come here for the wonderful theater. There are a good number of LNP(language no problem) productions as well, which is good if you are learning Dutch, or even if you have no intentions of assimilating. The bar/restaurant is nice and cosy, even for groups, and serves good entrees, including vegetarian options. Decently priced, great performances, and you get to support the local arts scene. It’s a good bargain.
