Hell's Kitchen has been filmed in several locations over its many seasons. Initially, most seasons were filmed at studios in Los Angeles, California, with specific locations including West Hollywood, Culver City, and Burbank. More recently, the 19th and 20th seasons were filmed in Las Vegas at the Caesars Entertainment Studios near the Las Vegas Strip. Starting with the 23rd and 24th seasons, the show moved to a brand-new custom-built set inside Foxwoods Resort Casino in Mashantucket, Connecticut. This marked the first time the series was filmed entirely on the East Coast, with the new studio showcasing Foxwoods prominently in the episodes.

To summarize:

• Early to mid-seasons: Various studios in Los Angeles area (West Hollywood, Culver City, Burbank)
• Seasons 19 and 20: Caesars Entertainment Studios in Las Vegas, Nevada
• Seasons 23 and 24 (current): Foxwoods Resort Casino, Mashantucket, Connecticut

This reflects the show's filming history and its recent relocation to Connecticut for the latest seasons.
