The vegetarian counter is one counter (with its own label) in a food court with many meat, fish and seafood serving stalls. Yes, veggie food is picked up by customers (and largely cooked) separately from the other stalls. But economically the food court is one overwhelmingly non-vegetarian restaurant, with the staff of the vegetarian counter likely not to be vegetarian and a supply chain that is shared with the other stalls. Something to keep in mind.
Otherwise, as already stated, it's cheap, tasty, clean - very handy indeed.
Cons: part of a 90% non-vegetarian operation
