US Lanka is a small Sri Lankan-owned grocery store which also makes some bakery goods and appams. My friend has ordered idiyappam (aka string hoppers) from here on multiple occasions. They are made to order on-site and have come out hot & fresh both times I had been party to the meal. Along with the idiyappam, they give you coconut sambal (grated coconut seasoned with red chilli, lime, sugar, etc.) and paal sodhi (a think, light coconut milk curry).
As for groceries, it's a small store so don't expect a huge inventory. They do have many different Sri Lankan favorites (pickles, snacks, refrigerated items like fish, drinks, mixes to make curries/dishes, etc. Since we have really only come here for the idiyappam and accompanying items, I can't speak for the quality of the grocery items.
I will say, however, that while we were waiting for our order of 50 idiyappam, several of their savory pastries were snatched up by a handful of customers, so I suspect they do a good job with those. From what I eyeballed, it looks like those were chicken rolls, fish rolls, and such. Next time, I'll have to ask about those and give them a try since I have liked these snacks when I have eaten them at other Sri Lankan stores.
