I've just returned from the Japanese Street Festival in Downtown DC, and I was sorely disappointed. There was an overabundance of nasty non-Japanese food (lots of tents that had fried rice, egg rolls, pad thai, and chicken teryaki - the only remotely Japanese food), then there were tents with sushi. I spotted a tent serving some sort of soup, which tasted like a corn soup (it wasn't very good). I don't know if I just missed the tents serving the good, authentic Japanese food, but it just wasn't good at all.
The whole thing made me wonder if there are any good cultural festivals in the DC area. I used to live in Houston, and there were some excellent festivals there that different churches put on (there was a huge Greek festival with the best food made by the congregation of the Greek orthodox church that held it, and another excellent Egyptian festival put on by a Coptic church - it had the best dolmas I've ever had). Generally the better ones are held by churches or cultural associations and aren't city sponsored. Are there any good ones here? I've read about the DC Festa Italiana - how's that one?
Any suggestions in DC or NoVA are welcome (and possibly in MD, but I'm not really crazy about driving to Baltimore).
