Thanks for the review. We are English/Thai owned and offer a mix of Thai and western food in the heart of the tourist area. This should explain the number of western customers and the lack of Thai authenticity! Glad you enjoy the more authentic feel and prices of the Thai owned restaurants but just a heads up - you're almost certainly not eating vegetarian. All my kitchen staff confirm that when you order Tom Yum, Massaman etc, most Thai establishments use a pre bought paste that will contain shrimp paste and/or fish sauce. Maybe that is the taste difference in your Massaman. If this upsets you I'd strongly recommend sticking to veggie places or places like my own that clearly mark the dishes and make them separately!
