Japan was the first place I tried good Indian food 3 years ago. Since then I have searched far and near for a comparable Indian restaurant and finally found Chennai Masala. I have tried over ten items from the menu and all have been outstanding! The vegetarian selection is very extensive.
Excellant review about their buffet, look in oregonlive.com, and search for Chennai. By far the best south indian selections i have ever tried.
Their Deserts are also so unique unlike the every predictable rice-gheer, payasam or gulabjamoon. The best dosas i have tasted after i came from Bangalore.
The place is a bit small, but if good quality food is our choice. it wont keep you away.
Catering we did a special catering, and they do any items you request thats not on the menu as well... Try their Lamb Chukka.. the best lamb i have ever tasted..
