Chautara is partnered with Himal Chuli, and it represents the more meat-centric side of the spectrum, while Himal Chuli is more veg. There are plenty of veg options at both places, but the veg items are listed second at Chautara, with fewer choices, and first at Himal Chuli, with lots of them. Chautara is a safer bet when you're dining with omnivores, as they will probably be more comfortable with the atmosphere and choices. If you're with your veg friends though, go to Himal Chuli. The quality of the food is the same, in my opinion, quite good.
