11:30 Remy brunch followed by a 7:00 Palo dinner? Whoa! I would definitely still be too full from brunch to go to dinner that early, esp. with it being brunch & dinner @ Remy & Palo. We even try to avoid doing dinner at one of them one night followed by brunch the next day. If you absolutely must do them both on the same day, try to get into brunch earlier and push your dinner back as late as possible. Just my suggestion.
As for the denim, no, I would not wear that. Nor would I wear any character clothing to Remy or Palo. Even if the items are dressier, having the characters on them somehow (in my mind) negates some of the dressiness, if that makes sense.
HTHs!
