Help us find two different types of high chairs?

What should we do about this when we go to restaurants?. I would love to get her all the way up to be able to eat comfortably and be a part of the conversation, not just under the table. We would need to find something for both chairs and booths that could be adjustable given that at each different location the height are really different and not really known. We have tried the boosters that they provide and that usually only brings her high enough for us to only see the very top of her hair, or for her to be able to barely see over the table when she stretches up as high as she can, and in booth she still isn’t close enough.

The ideal highchair that we are looking for at home would be one that is able to slide under the table a little while also having a seat high enough so Clara can sit right up at the table and rest her feet in the highchair and eat from her plate. We can help her with everything else that is too far for her to reach, but at least she would be able to reach her plate nice and comfortable. also if there was a latter for her to climb up by herself. We could modify the existing ladder on the backside and switch out the handles for much smaller ones and even add a couple lower so she can be able to reach them. Unlike a traditional baby/toddlers highchair which only brings them up high to the table but they are still sitting pretty far back because they are being helped with feeding and other things.
