Meet Up!
Do you have an interest that you want to share with other aficionados? Then check out this website:
MeetUp.com
This website is the end all be all to any type of social activity group you might be wanting to find. It connects you to people that share your same interests and if you are the type of person that likes to initiate then you can start your own group.
I've used this website when traveling to parts unknown where I don't know anyone or if whoever I'm visiting is working and not able to take me around town so to speak at all hours of the day.
I met an interesting group of sushi lovers out in the San Francisco Bay area a few years ago. They get together every so often to try out different sushi. I'm not as adventurous when it comes to raw fish and usually opt for the tempura roll or sweet potato roll, etc. However I do enjoy Japanese food like shrimp tempura and beef teriyaki. I especially like something called beef yakiniku which is absolutely delicious. I think it rivals Korean bulgogi, but don't tell any Koreans I said so.

If you are gluten-free and looking for a good soy or teriyaki sauce alternative then try San-J products. This is a tasty alternative to the normal soy sauce products and safe for celiacs. San-J products can usually be found at Whole Foods or Giant Eagle Market Districts.
