Here is a glimpse of the food and menus in the Varkala area (November 2013).
Some of the pictures are not clear, apologies for that.
There appears to be very little, if at all, Kerala cuisine in the restaurants up on the cliff. Mostly continental, Chinese and Tibetan. Cooked predominantly by Nepali boys. Several signs indicating vegetarian and organic food.
Tuna grill, without butter, very little oil, without rice and chips (my request), with additional salad and veggies (in lieu of rice and chips).
The bakes counter. Look don't touch (for me!).
View of the path, cliff and beach from the restaurant.
