During my visit to Jaisalmer in March this year, I walked a lot to feel the vibes of the city and got tired hence hungry quicker than usual.
The tour guide recommended the Chandan Sri Hotel that is right in front of the Jaisalmer Golden Fort. They had a sweet shop on the ground floor and a dining hall on the upper floor.
The sitting arrangement was retro with all-wooden tables and chairs.
The main attraction was self-service racks from which one could take the necessary dishes, paper napkins, spoons, and cutlery as required.
The food was served at the table and the service was prompt and quick. They have an elaborate menu.
I chose the Veg Thali which was unlimited and had 2 vegetables and one Daal with rice and unlimited rotis + a choice of dessert from Rasgulla or Gulab Jamun.
My favorite dish was the Tomato-Paneer curry that I got refilled 5 times 
The best part was the limited and clutter-free Thali at nominal rates that were well-suited for a quick bite and get back on the road again.
