We have been to Chotto Matte last year, which you can read about here. Overall we thought it was quite enjoyable, if a bit steeply priced. We have not tried their other locations.
We have been to Mira twice, the last time early in the pandemic. We also enjoyed it (enough to go again), though we can’t compare much as we tended to stick with the more Peruvian dishes. The giant chocolate ball dessert was particularly fun, but I think it has disappeared from the menu.
