There is small restaurant in Dublin, CA called Kadupul run by a couple from Sri Lanka. Every since I found them on a rainy cold December weekend two years back, I have always enjoyed their food.
This cuisine is spicy (can be less spicy like Thai), but can be much more spicy if you tell them to. The spices they use are different from India and south east asian countries and that uniqueness makes me crave for their food.
I saw such intense liking for all types of food on this board and that motivated the new forum member in me to share my liking. They serve buffet for lunch during weekdays - some of the stuff in the buffet are unique like raw Jackfuit curry, crab curry, etc. Since I prefer my curries more spicy that a buffet wouldn't be, I always order a la carte.
On weekend nights (Fri, Sat), they make thin pancakes called Hoppers (Appams in Southern India) that you can order with Goat Curry, Beef Curry, Chicken Curry and this is my favorite - Wild Boar Curry! They also have a noodle like dish called String Hopper that goes with the same curries.
The only shortcoming is that they don't serve alcohol, but you can bring your own. And they have some great ayurvedic teas.
On weekdays/nights if I happen to go there, I order Buryani (like Indian Biryani) - they can make it with rice, string hoppers or with chopped up paratha (flat bread).
This place is a must for folks who enjoy spicy food.
I got hooked to this cuisine when I started visiting Toronto (Canada) where they have many Sri Lankan restaurants.
