I tried out Rosa for the first time in June 2023. I was excited to have more Mexican options at Disney. I found it OK - but not overwhelming. Staff was exellent and friendly, decor was very nice, the drinks were very good, the salsa and chips were fresh. I had the Queso appetizer - it was a little on the bland side even with the chorizo, but not 'bad'. Chicken enchiladas were similar. Nothing was bad, all was fresh, and I still went home full - but it didn't stand out as a must-have.
I'd be willing to go again - at the moment I'd consider it a backup choice, and I leave open that it could have just been the dishes I chose weren't as exciting, or could have been an off night. I do still prefer Hacienda de San Angel's Mexican food.
