Family restaurants, or "famiresu," as they are often called in Japan, are a type of restaurant that's ubiquitous throughout the country. Denny's, Royal Host and Jonathan's are examples of famiresu chains.
100 Spoons, in the Tokyo neighborhood of Futako Tamagawa — specifically the Rise Shopping Center — bills itself as a "new" type of family restaurant that aims to be a special destination for families while still offering the broad selection of dishes that famiresu are known for.
To be honest, family restaurants tend to be a last resort for our household — it's where we go when we can't reach a consensus about what to eat and cooking is out of the question. I wasn't entirely sure what to expect at 100 Spoons, but am happy to say I was pleasantly surprised.
