i've ordered fan si pan a few times for delivery... they have super efficient delivery, it seems... you can order online on grubhub. the first time i ordered the order came in less than 30 minutes. i think it even came by bike. the second time it was a more normal 45 minutes but the lady was apologetic and nice..
they have mochi--my new favorite dessert perhaps--and for delivery they even put them in a bag that was then put inside a bag of ice... i can speak from experience that other delivery places don't do this, and the product came melted from those places... (though on grubhub's online ordering they seem to have--perhaps purposefully--left out mochi as a delivery option. i just wrote it in comments)
and for the food... i really like their beef spring rolls ... chicken was oK, not great not bad. i really disliked the curry shrimp. SO had a bahn mi sandwich--pate sandwich which was good. i like the papaya salad. the free rice dessert they give you isn't anything too exciting, but edible.

1/2 curry shrimp roll (kinda "ehh" in my book)... 1/2 5 star beef spring roll (great!) .. green papaya salad w/ both:[/url]
what I really like about the place is it's price. you can order a meal for 2 and have it delivered for $22 after everything, and still have food left over.
