When they say "firecracker" they mean it. This is spicy even if you're used to Middle Eastern / Indian kind of spicy. We loved it, but it's not for the faint of heart :-)
Great dependable food at low-to-mid range prices. Harvard square really needed this. A new go-to place for us, solves many "where should we eat" arguments!
you orrery much can't go wrong w/ any of the ramen or grilled noodle dishes. I always get a fresh juice and a side of Japanese pickles with whatever I get.
If you're by yourself, get a window seat. I ordered the seafood ramen (if you can bring yourself to buy a $15 bowl of ramen). It does come with a lot of fish and other stuff.
