The Short Version
Misleading. Some restaurants in Delhi, Mumbai, and Bengaluru have trimmed butter chicken from menus in March 2026, but the cause is an acute LPG supply disruption triggered by geopolitical tensions in West Asia — not generalized "rising operational costs." The claim overstates both the geographic scope ("across India") and the nature of the driver. These menu changes are crisis-conditional and concentrated in a few metros, while butter chicken remains widely available elsewhere.
